provide pre- and post- hooks with parsed command line arguments.

python hooks are passed two new keyword arguments:
- opts: a dict of options; unsepcified options are set to their default
- pats: a list of arguments

shell hooks receive two new variables containing string representations
of the above data:
- $HG_OPTS
- $HG_PATS

for example, the opts and pats for 'hg -f v1.1' would be:
{'force': True, 'message': '', 'rev': '', 'user': '', 'date': '', 'local': None, 'remove': None, 'mq': None}
['v1.1']
