    SourceLanuageManager::guess_language(): Correct the reference counting.
    
    	* gtksourceview/src/sourcelanguagemanager.hg: guess_language(): Use
        refreturn. This fixes  a crash in regexxer.
    	* gtksourceview/src/sourcebuffer.hg: get_undo_manager():
        Use refreturn with _WRAP_METHOD() and actually implement (via _WRAP_METHOD),
        the const overload.
    	* gtksourceview/src/sourcecompletion.hg:
    	* gtksourceview/src/sourcecompletionprovider.hg:
    	* gtksourceview/src/sourcelanguage.hg: Added some TODOs for minor stuff that
        I noticed while making these changes.
