[PATCH/RFC 3/4] git-mw: Adding git-mw.perl script

[benoit.person@xxxxxxxxxx]

From: Benoit Person <benoit.person@xxxxxxxxxx>

This script will be used for all tools and command related to a mediawiki
remote. In this commit we introduce the tool, the way it parses argument
and subcommands and an example of subcommand: "help". It also updates
the Makefile so that the new tool is installed properly.
