114726 - platform-specific contractIDs in widget

Status: NEW

In many parts of the widget code there are platform-specific contract IDs.  That
doesn't make much sense, since they can't be used.  As I understand it, the
point of contract IDs is to allow for multiple implementations to be swapped in,
whereas each implementation should have a unique CID, or something like that. 
I'm not against GFX having the same CID for multiple implementations since CIDs
are probably more efficient.

But anyway, the bigger problem is that we have tons of contract IDs all over the
widget factories that are useless.  We also have some that have been commented
out in the GFX factories.  And there are also some implementations of timers
that use a different CID for timers other than NS_TIMER_CID.

This should be cleaned up.  I'm assigning the bug to myself, although I don't
intend to do it in the near future.

A few of these were fixed by bug 211360.

We still have the weird platform-specific contractIDs.  (Not that we should really even be *using* contract IDs here if things aren't swappable...)
