Commit c9c885a84143763c22ec98522a46fcb2807b420c - xapp

Add XAppFavorites. Favorite files are stored as a set of (uri, mimetype). During runtime, however, a 'display_name' field is computed and is also available. If the file's basename is unique among all favorites, this display_name will equal the file's basename. Otherwise, the file's parent folder is also displayed as part of the display_name. - Favorites are stored in dconf. - Interaction is via an XAppFavorites (singleton) class which allows adding and removing, and activating, along with lookups. - Favorites can be listed in their entirety or filtered by a mimetype or list of mimetypes (so apps that handle specific mimetypes can retrieve only favorites they can handle). - Utility functions are provided to retrieve a GtkMenu containing menuitems corresponding to favorites, as well as a GtkActionGroup for the same. The menu one is maintenance-free and will update its children if the underlying list of favorites changes. The action group is not. Favorites uri: - A 'favorites' uri scheme and GFile implementation is added using a GtkModule to allow programs to access favorites as though it was an actual folder. - The module also adds a "Favorites" shortcut to all Gtk3 file-picker dialogs to allow selection there. Issues/TODOs: - When implemented in other apps, activating/opening a favorite file will add it to the recent file list, unless specifically filtered out in the app. This isn't desirable, since by definition a favorite file is probably also a recent file, so they needn't be shown in both lists. - While the favorites:/// uri can be accessed by any Gtk3-based file manager, it's a poor experience unless specific handling is added. - The icons in this commit need to be replaced, except perhaps for the two symbolic actions. Initially, support is added to: - nemo (full support, adding, removing, sidebar, etc...). - xviewer (menu access to favorites). - xreader (menu access and launch landing page view). - pix (Favorites entry in the sidebar tree). - xed (menu access to favorites). - cinnamon (dedicated favorites applet, and a category in the menu applet). - warpinator (menu access in the 'send files' popup as well as the status icon menu).

	31	*
	32	* In gtk_module_init, the XAppFavorites singleton is initialized, and
	33	* the 'favorites' uri scheme is added to the default vfs. Ordinarily
	34	* non-file:// schemes aren't supported in these dialogs unless their
	35	* 'local-only' property is set to FALSE. Since favorites are shortcuts
	36	* to locally-available files, we lie to the chooser setup by returning
	37	* "/" instead of NULL when g_file_get_path ("favorites:///") is called.
