added a mercurial commit script

	* contrib/hg_buildbot.py: wrote a commit script for mercurial, to
	be placed in the [hooks] section of the central repository (the
	one that everybody pushes changes to).


--- NEW FILE: hg_buildbot.py ---
#! /usr/bin/python

# This is a script which delivers Change events from Mercurial to the
# buildmaster each time a changeset is pushed into a repository. Add it to
# the 'incoming' commit hook on your canonical "central" repository, by
# putting something like the following in the .hg/hgrc file of that
# repository:
#
#  [hooks]
#  incoming.buildbot = /PATH/TO/hg_buildbot.py BUILDMASTER:PORT
#
# Note that both Buildbot and Mercurial must be installed on the repository
# machine.
