Remove "detachable toolbar" option from the ui properties capplet (Bug #408295)

[Bastien Nocera <hadess hadess net>]

Heya,

I was interested in getting the detachable toolbar option removed from
the ui-properties capplet. The reasoning here, copied from the bug:
---8<---
The detachable toolbar doesn't work well. Most applications don't use
Bonobo,
or its toolbar, so they can't be detached anyway. Given that only a few
BonoboUI-powered apps are left, and that most bug reports about that option is
that it doesn't work for such and such application, I think it should be
removed from the UI, and made into a GConf-only setting.

An example bug report:

The patch at http://bugzilla.gnome.org/show_bug.cgi?id=408295#c4 does
just that.

Any comments before I get this committed?

Cheers
