[PATCH] Allow explicit disabling of extensions

[Steve Borho]

This doesn't qualify as an urgent patch.  It hardly tops 'would be nice'
on the priority meter, but I would like it to be considered.

My initial reasoning here:
http://marc.info/?l=mercurial&m=119009384627980&w=2

And a few more comments here:
http://www.selenic.com/pipermail/mercurial-devel/2007-September/003023.html

I know there's a certain hackish quality to the patch, but I'm unaware
of any other way to get equivalent functionality.
