Merge lp:~jelmer/lptools/command-option into lp:lptools

[Jelmer Vernooij]

Add a -c option to lp-shell.

Example:

Am I a Ubuntu developer ?
$ ./bin/lp-shell -c 'print lp.me in lp.people["ubuntu-dev"].participants'

[Martin Pool (mbp)]

> run the specified Python program

[query] I wonder if people would expect 'program' is a file containing a program. You could add an example or say eg 'code'.

review: Approve

[Jelmer Vernooij (jelmer)]

Thanks, merged with a tweak to the option description.
