Add GtkApplication

Browse Source 
This is a work in progress to stub out an application class. The
primary goal is to provide a mechanism for applications to export
GtkActions, and there is a standard "Quit" action.

This is based on GApplication.

Future work:
 * Add a way to say "This is my application menubar", which gets
   put into all toplevel windows on non-OS-X, and into the top
   on OS X.
 * Support session management.
 * Support application settings.

It also mentions how to convert applications using widgets
found in the libgnomeui library to use their counterparts

* @short_description: Application class
*
* #GtkApplication is a class that handles many important aspects
* of a GTK+ application in a convenient fashion, without enforcing
* a one-size-fits-all application model.
*
* Currently, GtkApplication handles application uniqueness, provides
* some basic scriptability by exporting 'actions', implements some
* standard actions itself (such as 'Quit') and provides a main window
* whose life-cycle is automatically tied to the life-cycle of your
* application.
