Log Message:
-----------
finally after a burst of inspiration I've figured out an easy way to add
support for new right-click options on any resource without using a VR (which
is a pain because you have to open the VR to get the options). It uses the
existing tool support but with a parent class of ResourceHelper instead of
implementing ActionPublisher -- this should be considered experimental for now
and may change before the next release of GATE
