omega 8.x-5.0-alpha4

Lots of updates, but primarily an update to provide the OmegaExport class that handles the cloning of, subtheming of Omega Five themes from the Interface.

To get started, enable Omega, and go to the settings page. This will allow you to create a clone of one of the default Omega Starterkits. You could also subtheme a starterkit, however when creating a 'real' theme, and not just testing, you wouldn't want the starterkit as a base theme of anything in your theme inheritance chain.

Once you've cloned a theme, you can then alter, adjust, etc. and then create a clone or subtheme of that theme as well.

When creating a subtheme, various logic is considered and a few options present to provide a theme-settings.php file, empty js/css library, theme file example functions, etc. This functionality will be further hashed out/debated later in what we want exactly to be able to do when using this feature.

I've already used the feature extensively in testing creating multi level deep subthemes, and can see the feature being nice to handle making a clone of your subtheme that will allow you to test an internal patch against a theme/subtheme.
