Subject: Remove duplicated template code.

Content-Type: text/plain; charset=UTF-8

Unify TypeDefinitions specializations. I'm not aware of any reason why
QVariant should have a separate set of supported types during
bootstrapping phase. It would cause only crashes.

As a side effect the patch reduces size of core and gui libraries.
