desktop: Remove obsolete Bugzilla entries

See merge request !23

The X-GNOME-Bugzilla-* entries were for use by bug-buddy, a GNOME 2
technology that's been gone for over a decade. These entries are
obsolete and can be removed.

interface_view: Drop manual click handler that runs into exception

See merge request !22

Clicking into the `GtkTextView` that is used to display
and edit the text via the text interface resulted in
this exception being printed on stderr:

    Traceback (most recent call last):
      File ".../accerciser/share/accerciser/plugins/interface_view.py", line 1453, in _onTextViewPressed
        self.offset_spin.set_value(iter.get_offset())
    AttributeError: '_ResultTuple' object has no attribute 'get_offset'

Retrieving the offset from the `_ResultTuple` in
`_onTextViewPressed` could be fixed as follows:

    -    self.offset_spin.set_value(iter.get_offset())
    +    self.offset_spin.set_value(iter[1].get_offset())

However, `_onTextCursorMove` is already registered
as a handler for cursor move events, and also gets
called when the cursor gets moved by clicking into
the GtkTextView using the mouse. Since
`_onTextCursorMove` already takes care of updating
the offset in the spinbox, there seems to be no
need for `_onTextViewPressed`, which was meant
to do exactly that, so just drop it.

Take over a helpful comment from its doc
to `_onTextCursorMove`.

ipython_view: Fix off-by-one number in input prompt

See merge request !20

Previously, the numbering for the input prompt
was incorrect, one too low except for the
first prompt, so there was a mismatch between
the numbers for input and output: An "In [n]"
would be followed by an "Out [n+1]", e.g.

    In [1]: 1
    Out[1]: 1
    In [1]: 2
    Out[2]: 2
    In [2]: 3
    Out[3]: 3
    In [3]: _i2 # should give the input with index 2
    Out[4]: '2'
    In [4]:

Fix this by generating the next input prompt
*after* the current input has been processed
(`self.IP.run_cell(source_raw, store_history=True)`),
at which point the counter (`self.IP.execution_count`)
has the correct value:

    In [1]: 1
    Out[1]: 1
    In [2]: 2
    Out[2]: 2
    In [3]: 3
    Out[3]: 3
    In [4]: _i2
    Out[4]: '2'
    In [5]:

ipython_view: Add keyboard shortcuts to clear input after cursor (Ctrl+K) and copy selection (Ctrl+<uppercase>C)

See merge request !19

This adds the functionality to copy the current selection
in the iypthon_view to the clipboard
by pressing Ctrl+C (upper-case 'C' only).

Ctrl+c (lower-case 'C') is already used to trigger
a keyboard interrupt.
Use Ctrl+C (upper-case 'C') as an alternative
to copy text as e.g. various terminal emulators (like
gnome-terminal or konsole) also do.

This makes it a bit more readable/clearer that this is
about pressing Ctrl+c.

This adds the functionality to clear the text
after the input cursor in the iypthon_view when
pressing Ctrl+K (with either lower- or upper-case 'K'),
as is possible when running a standalone interactive
IPython shell in common terminal emulators.

ipython 8.0 seems to be using more than the very standard ANSI 16 colors.
I didn't find exactly where this is coming from, so just adding the few
cases that show up on exception raises.

ipython 8 dropped it, and it seems that the sys.{stdin,stdout,stderr}
redirections work correctly now.

Fixes #52

treeview: Make selecting bookmark work on first attempt

See merge request !18

Accessing the given path in the model can
fail if the items have not been populated yet.

Therefore, try to access the given path again
right after populating the model to the
given path.

To make sure the model has actually been
populated, process all pending events
after the call to `self.model.popToPath(path)`
since populating is done via idles
(s. `AccessibleModel#popLevel`) that may
otherwise not have been processed yet.

This makes expanding and selecting the
corresponding item in the treeview work
when clicking on a bookmark for the first
time, while it required clicking the bookmark
a second time previously if the path had not
already been populated.

(The documentation for `selectNodeAtPath`
already claimed this:
"The path does not need to exist in the model,
only in the accessibles tree. The model will get
populated accordingly.")

treeview: Use filtered path to select correct entry when navigating to bookmark and "Show applications without children" is inactive.

See merge request !17

The gtk.TreeView methods called in `_selectExistingPath` operate
on `AccessibleTreeView`'s model, which is the filtered model
(`self.filter`, s. the call to `self.set_model(self.filter)` in the
`AccessibleTreeView` constructor).

Since the path to the unfiltered model (`self.model`) gets passed
as a parameter, convert this to the filtered path before using it to
select an item.

This fixes navigating to a bookmark when
"View" -> "Show applications without children"
is disabled (the default), which was otherwise using
a too large row index in the path if any hidden applications had
a lower row index than the bookmarked application.

Validate: fix the wiki URL to Accerciser pages

See merge request !15

Accerciser's page got moved under Apps a while ago; also, the wiki is
now wiki.gnome.org instead of live.gnome.org.

ipython_view: Clear output on Ctrl+L

See merge request !13

This adds the functionality to clear the old
output from the iypthon_view when pressing
Ctrl+L (with either lower- or upper-case 'L'),
just as is possible on a standalone interactive
IPython shell.

If anything was typed in the current input line,
that text and the cursor position are remembered
and restored.
