wow 7.x-2.0

This is an important upgrade containing architecture changes.

Several bugs has been fixed, through the test suit.

More than 500 unit, functional and integrations tests has been written.

Documentation page and developer handbook is being written.

This release contains a lot of refactoring to follow drupal conventions and preparing 8.x releases. You will notice that PSR-0 conventions is also used, although the loaders does not make use of it now. This is just at folder-level.

I initially planned to write a full release log, but I will do it properly in the dev handbook. The API should be now pretty stable and only minor fixes may be committed. Here are the steps to upgrade:

1. Important: Disable the WoW Guild Rank module before any atempt to upgrade to 2.x. Do not uninstall it, just disable it.
2. Download and install the entity module.
3. Put your site in maintenance mode and visit the update.php script. Apply the updates and check nothing has failed.
4. (Optional) If you previously disabled the WoW Guild Rank module, you can re-enable it.
