The language support plugin cannot control the methods, which are 
implemented with IAnjutaProvider. For example 
sourceview_provider_activate_proposal() [1] calls 
ianjuta_provider_activate(). If only IAnjutaProvider is implemented, 
then the method is realize in the class, which implements 
IAnjutaProvider (i.e. the sippets-manager plugin). But if 
IAnjutaLanguageProvider is implemented, then 
sourceview_provider_activate_proposal() should calls the 
ianjuta_provider_activate() method, which is realize in the sourceview 
plugin [2].

The language support plugins don't need to implement IAnjutaProvider, 
because populate(), get_start_iter() and activate() are already 
implemented. [3] Only get_name() will remain unaffected.
