[PATCH] contacts: allow execution from other directories

[Thomas Gummerer <t.gummerer@gmail.com>]

Currently git-contacts only works if it is executed from the top level
of the git repository.  Enable the execution in sub directories of that
repository.

I have no experience in perl, so there may be nicer implementations.  It works when tested manually.
