Add support for non-GObject fundamental objects

This patch adds support for instantiable fundamental object types,
which are not GObject based. This is mostly interesting for being
able to support GstMiniObject's which are extensivly used in GStreamer.
Includes a big test case to the Everything module (inspired by
GstMiniObject) which should be used by language bindings who wishes to
test this functionallity.

This patch increases the size of the typelib and breaks compatibility
with older typelibs.
