Introduces RequestFactory interface and "tool generated"
interface ExpenseRequestFactory.  Moves old
ExpenseRequestFactory class to become "code generated"
ExpenseRequestFactoryImpl, in new package gen.

Introduces @LongString and @ServerType annotations

Various other renames: Entity > EntityRef, and Ref
suffix added to clients side entities to avoid
confusion with server side.

Lots of checkstyle
