[Python-apps-team] Bug#824512:

[Neil Muller]

I've forwarded the template override option upstream, since it looks
generically useful to configure the output of irker.

Since irkerhook.py defaults to sending messages to #commits on
freenode, I would rather not make it too easy to send messages without
a project being specified. irkerhook-git is intended as a convient
helper, rather than the only way to configure things. People who need
different behaviour from the default can easily change the commit hook
to suit their requirements. I'll look at expanding the manpage section
on this.

The hook should arguably not fail silently by default if things aren't
fully configured, though - I'll see about adding some more informative
message to the failure path.
