Missing documentation

[Speedy1991]

I just tried around with your fabdeploit and got this error:

fab -u git -H localhost deploy
[localhost] Executing task 'deploy'
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/fabric/main.py", line 757, in main
    *args, **kwargs

    self.create_release_commit(message=message)
  File "/usr/local/lib/python2.7/dist-packages/fabdeploit/git.py", line 226, in create_release_commit
    commit = repo.heads[self.release_branch].commit
  File "/usr/local/lib/python2.7/dist-packages/git/util.py", line 893, in __getitem__
    raise IndexError("No item found with id %r" % (self._prefix + index))
IndexError: No item found with id 'master'

Steps to reproduce:

• use the django example from docs
• setup a simple django app
• git init
• git checkout -b master
• fab -u <user> -H <host> deploy

Solution:
The master/production branch must be commited (inital commit is enough) before running fab. This is not really an error in my eyes, but some documentation would be nice

Good catch!

Feel free to open a pull request ;-)
