uuid 7.x-1.0-alpha2

This release is a major rewrite of the 7.x-1.x branch and breaks backwards compatibility with 7.x-1.0-alpha1 !

An upgrade path from 7.x-1.0-alpha1 won't will be provided.
An upgrade path from 6.x-1.x will be provided, once we reach beta.

There are some better in-line documentation and uuid.api.php is updated. But a more complete API documentation will come for the beta release!

Some of the major changes are:

• Generic entity support. We no longer have sub modules for every entity type.
• Support for loading entities so that they only contain UUID references in properties and fields.
• Support for saving entities containing only UUID references.
• New ID and UUID lookup functions.
• Mush better test coverage, almost 100%.
• The OOSP generator was dropped as the underlying PHP module is badly broken.
• UUID for user roles aren't implemented in this release yet. But it will be!
