Added git information to version string

Browse source 
Running ansible --version now outputs git information when the
repo lives in .git in the root of the ansible source (coping with the case
where the git info is elsewhere is left as an exercise).

This uses gitpython where installed, otherwise it interrogates the files
in the .git directory to get the same information.

The gitpython path could be removed, but then people might ask 'why did
you do it like this when gitpython exists'
