Hi,

I want to request a $subject, executed unconditionally on project save after config is loaded but before the actual save (similar to "configuration-save"). It'll serve the following purposes:

1. Let a plugin undo any temporary project / file setting changes it possibly did, before the save takes place.

2. Allow saving project settings which are not part of the project dialog. The current signal, "project-save", is executed only on Project Dialog -> OK / Apply, but not when a project is closed, and consequently not on Geany quit.

3. Allow saving plugin project settings on project close (and Geany quit) to an empty file, for example project-<x11-session-id>.geany - same problem as #2.

The code is attached, courtesy of Jiří Techet, and works fine.

Now, #2 and #3 may be solved by making "project-save" unconditional, but that will break compatibility. #1 can be done by g_key_file_get/ set with the config argument of "project-save", provided it's unconditional, but I'd prefer to use a documented plugin interface instead of opening the bag of tricks.
