This way there's less redundancy, and if the library name changes in the
future, it will be changed only in one place.

GSource type was already there (but was not mapped by
the generator yet) so then the autogenerated methods
have been added manually inside the class after the
custom methods.
Other Source-related class are also generated and added
(but not mapped in the SymbolTable) to glib.
