[PATCH/RFC V2 0/4] git-remote-mediawiki: new tool to preview local changes without pushing

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

The #7 issue on git-mediawiki's issue tracker [1] states that the ability to preview content without pushing would be a nice thing to have.

This serie is a second attempt to achieve it:
  - It adds a new GitMediawiki.pm package to share code between the new tool and 
    `git-remote-mediawiki.perl`. (PATCH 1 & 2)
  - It creates a new "meta"-command `git mw` with subcommand handling (PATCH 3)
  - It adds a new subcommand named `preview` to `git mw` (PATCH 4)

changes from the V0:
  - add new package GitMediawiki
    - move some of git-remote-mediawiki functions into the package
    - update git-remote-mediawiki to use those "moved" functions
    - add a hacky-way to install it in the Makefile
    - use it in the new git mw tool
  - add a way to give to the preview tool blobs as argument
  - add a fallback when the upstream's branch remote is not a mediawiki remote
  - update the `autoload` option to use `git web--browse` and not `xdg-open`
  - update the way we find the upstream's branch remote name

For now, this PATCH/RFC is based on the 'next' branch merged with the bp/mediawiki-credential patch. For the final version, I will try to rebase it on celestin's work with perlcritic.
