Privatized GladeClipboard members.

	gladeui/glade-signal-editor.c, gladeui/glade-command.c: Made GladeSignal an
	opaque structure with accessors.

	gladeui/glade-signal-editor.c, plugins/gtk+/glade-accels.c:

	Added glade-signal-class.[ch] as an opaque type.

	  (since we do it in expose and the view gets destroyed without us unsetting the pointer).

	Instead of privatizing GladeFixed, moved it to be a detail of the plugin backend.

	* plugins/gtk+/*.c: updated all custom editors to used eprop accessors now

	  src/glade-window.c:
	  - Removed glade_app_get_palette()
	  - Moved "pointer-mode" property from GladeApp to GladeProject
	  - Palette now in charge of driving pointer mode on the project it's registered to
	  - GladeWindow now watches/sets the pointer mode on the currently set project (with
	    its "selector" and "drag/resize" toolbuttons).

	gladeui/glade-popup.c, gladeui/glade-project.c, gladeui/glade-signal-editor.c,
	gladeui/glade-widget-adaptor.c, src/glade-window.c, src/main.c:
	- Removed glade_app_get_editor(), Now the editor is not overly-refreshed by the
	  core and editors can be created at will, the core doesnt need to hold on to one.
	- Also, "gtk-doc-search" signal has been moved from the GladeEditor to the GladeApp.

	  memory when releasing a widget name that was never allocated (this can happen
	  for loaded widgets with a number), fixes crash when setting naming policy for
	  glom_developer.glade.

	  - Removed GladeApp selection handling, only on the project now
	  - Removed "Copy" as a command, copying widgets no longer dirty documents (bug 546873)
	  - Removed GladeApp "active_project" concept, every interaction is associated with
	    a GladeProject
	  - Simplified GladeClipboard, the clipboard now only has a list of widgets and
	    not a "selection", everything is removed from the clipboard when new widgets are
	    added there.
	  - GladePalette now has a "project" property and does not need to be refreshed
	    by an external entity.

	  - Removed "update-ui" signal, This signal was encouraging bad behaviour and too much
	    action on every project change.
	  - Removed glade_app_create_undo/redo_button().

	* gladeui/glade-project.c: Stop calling glade_app_update_ui ().

	* gladeui/glade-window.c:
	  - Listen to GladeProject::changed instead of update-ui and only update the
	    undo/redo actions when the active project changes.
	  - Remove the preview toolbutton
	  - Add tooltips to important actions

	* plugins/gtk+/gtk+.xml.in: Mark the "preview" action as "important" so it shows
	  up in the app toolbar automatically.

	  project when the appropriate data changes (speeds up editing, with latest changes editing labels
	  in huge projects is smooth).

	  implementations... GladeProject already emits this after collapsing whenever the project
	  changes.

	  a single property instead of the whole widget when a property changes.

	* gladeui/glade-editor-property.c: Avoid infinite recursion when committing properties more
	  aggressively (found that editing text properties now make some recursion for some reason).

	  actually in the project from the GtkTreeModel interface.

	  make GladeApp properly destroy the clipboard when disposing.

	gladeui/glade-property.c, gladeui/glade-xml-utils.h, po/POTFILES.in:
	Completely removed GladeParameter, a legacy unused mechanism to store parameters in
	the glade catalog for later retrieval from the plugin.

	  Removing legacy 'old_project' argument from glade_project_add_object().

	  all commands reffer to that structure instead of trying to pull a project pointer from
	  a widget.

	* gladeui/glade-project.c: Unset project pointer on widgets when they leave the project,
	  manage an "in_project" flag on widgets to differenciate the moment when they widgets are
	  loading and have the project pointer but are still not added to the project yet. Also speed up
	  glade_project_has_object() by not traversing the list but simply checking the widget's project
	  and in_project flag.

	* gladeui/glade-widget.[ch]: Added the "in_project" flag to GladeWidget, fixed glade_widget_rebuild
	  to save the previous project pointer.

	  bug 634978.

	  object's value as a consequence of dupping (backend uses this to write properties with custom
	  values and does not expect that).
