Refactor GimpImageWindow session management. As far as session
management goes, there are four states and four transitions that are
interesting.

The states are:

 State    Window mode     Images opened
 ------------------------------------------
  s1          swm               0
  s2          swm              >0
  s3          mwm               0
  s4          mwm              >0

The transitions are:

  Transition     Description
 -------------------------------------------
      t1         Enter single-window mode (swm)
      t2         Enter multi-window mwm (mwm)
      t3         Open an image
      t4         Close an image

When thinking of it like this, it is pretty easy to see when to call
gimp_image_window_session_clear() and when to call
gimp_image_window_session_apply(). So kill
gimp_image_window_set_entry_id() and handle all transitions in
gimp_image_window_session_update().

This reverts commit c19560b0.
It was already included, don't know how I could miss that.

Make GimpToolbox and GimpToolPalette use the GimpUIManager and
GimpDialogFactory of the top container instead of holding references
on their own. If they hold references on their own, we need to update
these when we move e.g. GimpToolbox between different top level
containers such as GimpDockWindow and GimpImageWindow. Failure to do
this cased problems talked about in bug 646794 (case 2).

It's just weird not to.

When switching on single-window mode, put docks in the image window
depending on what side of the window they originally had.

When moving out GimpDock:s from a GimpDockColumns into a new
GimpDockWindow when switching off single-window mode, try to preserve
the size of the original GimpDockColumns.

It's enough to setup gimp_toolbox_drop_uri_list() on the vbox.

to set a frame's sensitivity instead of a signal callback. Also
improve tool options.

Distribute dock windows better when switching off single-window
mode. First, create one dock window per side of the image window
rather than one dock window per dock. Secondly, move the left docks to
the upper left corner of the screen, and the right docks to the upper
right corner.

The special case isn't pretty, but the current design can't handle it
nicely. This is not the first special case for the toolbox.

Pass gimp in gui_restore_after_callback() to
gui_restore_after_callback() so we can update properly.
