Extract git config variables as global dynamic variables

[fpringle]

It would be great to give the option to extract dynamic variables from the git (local or global) config, such as author and email. I assume there's an equivalent for other VCS systems.

e.g. a haskell.mustache file could look like this:

{-|                                                                                                                                     
Module      : {{{ _haskell_module_name }}}                                                                                              
Copyright   : (c) {{ _current_year }} {{ _git_user_name }}                                                                                     
License     : BSD-3                                                                                                                     
Maintainer  : {{ _git_user_email }}                                                                                                               
                                                                                                                                        
{{{ _haskell_module_longdesc }}}                                                                                                        
-}

Then _git_user_name would be replaced by the output of git config --get user.name, and likewise with _git_user_email.

Sounds good, thanks for suggestion! I'll look into it when I have some time.
