[PATCH V3 3/4] git-mw: Adding git-mw command

[benoit.person@ensimag.fr]

From: Benoit Person <benoit.person@ensimag.fr>

Add the new git-mw command, with its 'help' subcommand as an example. Argument
parsing and subcommand choice is based on git-svn.perl.
Update Makefile to build, install and clean both scripts now (git-mw.perl and
git-remote-mediawiki.perl).

changes from V2:
  - Perlcritic changes: 
    - Update for loops style to a more perlish one.
    - All 'print's specify their output streams.
