Clean command is undocumented (not included in
bundle help output), however that is very useful,
especially in RVM environment you can clean up
outdated gems in gemset.

git: fix parse_git_dirty()

If oh-my-zsh.hide-status is configured, the 'clean' code won't be
generated, and some themes might end up distorted. Let's generate the
'clean' code even when we don't want the show the dirty status.

gitfast: fix prompt

Certain themes need the 'clean' mark, and some people like to have the
'dirty' one, just like the original git_promp_info().

We probably shouldn't be modifying that function, there's no other clean
way to achieve our own status information, so let's try to emulate the
original as much as possible.

In this commit, the option only works for git but it should not be to hard for
someone who knows svn to so the same.
This commit is largely inspired by @yoavweiss, I only added an option to use
