Title: Added GUID expression to SQLite platform

This will add an implementation of getGuidExpression to the SqlitePlatform. It is based on [UUID version 4](http://en.wikipedia.org/wiki/Universally_unique_identifier#Version_4_.28random.29).

Don't know if this is appropriate, but I'm open to suggestions.
