refactored to allow default namespacing of User etc to verify bundle

- instances of \Verify\Models\User etc can now be called simple as User because they're mapped to \Verify\Models in start.php
- Role works a little differently, and the main models/role class extends to verify class.
Added class aliases for User and Permission to tests
