[Geany] SVN MyApp struct changes

[Nick Treleaven]

Hi all,
Just to let anyone working on the source code know, I've split up much 
of the MyApp struct from geany.h, and renamed it GeanyApp. Now only 
important fields are there.

Any plugins outside the project may be affected, but only minor changes 
(if any) will be necessary for compatibility. There is now a prefs 
field in the plugin API (see below).

Summary of changes:

New structs:
* GeanyPrefs (prefs) in prefs.h for (most) Preferences dialog fields.
* UIPrefs (ui_prefs) in ui_utils.h for non-Prefs dialog user interface
  related settings.
* UIWidgets (ui_widgets) in ui_utils.h for less commonly used widgets
  such as menuitems and dialogs.
* GeanyStatus (geany_status) in main.h for the various states the
  application can be in.

Some of the other MyApp fields were moved into EditorPrefs.

Any questions, just ask.
