garp composer

Garp has been made into an official Composer package.

That means the old subtree style is deprecated and Garp should be included in a project as a Composer dependency.

To help the migration, a Golem script was created.
After updating golem, the following oneliner will move you to the new setup:

g composer migrate

You have to manually delete the garp directory from the root of your project. Just make sure there are no changes left in there you wish to keep.

Note: Composer can be a bit whiney sometimes and you might want to add "minimum-stability": "dev" to the host project's composer.json.
