Indicator objects are not being disposed (and the dispose method is broken)

Status in Indicator Applet: New
Bug description:
When an indicator object is instantiated, it has a reference count of 2. This
is because it is incremented once in the gobject init function, and once in
indicate_server_add_indicator which the init function calls.
The indicators in the Pidgin plugin are not being disposed of for this reason,
since only one unref is called in the IM focus callback.
If a programmer hackishly brought the ref count to zero (by unreffing twice),
the indicator would run into an unref in the dispose function, because it calls
indicate_server_remove_indicator which does an unref (on an object with 0 ref
count).
My proposal would be to remove the ref/unref from the server add/hide
functions. Their GTK+ equivalents do ref/unref, but in our case the server is
singleton, and the adding/removing is done implicitly anyway.
This also raises a semi-related API question: Should the add/remove be in the
public API? It seems to me that since the server is singleton there is no need
for this. All that is probably needed is a destroy() of some sorts for explicit
removal. But hide() and a proper GC would do too.
