Matthias Clasen b0b38c106d Make gtk-im-context-none work
This was added a few years ago, as a way to have _no_ im context
at all. But it didn't actually work. Make it work, and streamline
the handling of none by moving it all to gtkimmodule.c.

As part of this, add context to the translated names of all
im modules we ship.
