Checks out and sets up the Odoo git repository for "internal" development.

* Checks out the "production" repository (production branches) as the "odoo"
  remote
* Checks out the "development" repository (for employee development branches)
  as the "dev" repository

By default, the working copy is "odoo"

Options:
-h        displays this help text
-m        includes github's merge refs. These are the pull requests to "odoo"
          which merge cleanly into the main repository, after having applied
          them to said repository
