[Trac] Adding SVN-like hook scripts for Trac events

[Matthew Good]

I have been thinking through some different things with Trac lately and
realized that it might be useful for Trac to provide something similar
to the way the pre-/post- commit hook scripts in SVN work.  These
scripts would be called for various events in Trac (new ticket,
milestone date changed, etc.).  I suppose once something like
http://projects.edgewall.com/trac/wiki/TracPluggableModules is
implemented this functionality could be wrapped up in there, but for the
short term a simple method of calling scripts would be an easier way to
add some more extensibility to Trac.

The thing that got me thinking about this was an idea for sending iCal
VTODOs to ticket owners.  I think this would be an interesting way to
allow users to keep up to date with their assigned tickets.  So, if a
ticket was assigned to a user, that person could be notified via email,
and if the milestone was set, it could send an update for the due date,
etc.  

Even more interesting, but challenging would be to actually monitor an
email address for responses such as accepting the task which would make
the appropriate update to Trac.
