Log:
This commit integrates Rob Jellinghaus' patches to the gwtjsf library,
making it compatible with GWT 1.4, enabling direct RPC access from gwtjsf
components to RPC server interfaces (no longer limited to GwtFacesService),
and providing full support for Seam. See http://unrealities.com/seamgwt
for fuller documentation and explanation. Also see this thread:
