[Glade-devel] Patch: Manage all the menu item sensitivities

[vgeddes at metroweb.co.za (Vincent Geddes)]

Hello Tristan

Have written code for the management of all the GtkAction sensitivities
in the user interface.


Overview
--------

1. Separated all the menu actions into two action groups:

   The actions in the 'static_actions' group are always sensitive,
   since the user should be able activate them even if
   no project is open.

   The actions in the 'project_actions' group are desensitized when
   all projects have been closed.

2. Detection of read-only files. Can now preempt users from trying to
   save a read-only project file.

3. Detection of correct state so that Cut/Copy/Paste/Delete actions
   can be carried out.

4. Hacked on the Undo/Redo code. No more "Undo: " labels if there
   is no command description.
