#63 Minor issue - Cut Vs. Delete

[Sushil Sureka]

It seems like there is no clear distinction between cut
and delete in GUI editor. For example the right click
menu(while working on query service) on the schema
node in the model editor does not give the delete option
(thought same can be acheived using cut but most of us
are used to seeing a delete when trying to delete the
stuff from GUI). But other places, like editing the class
descriptor do give a delete option.

A minor issue but if we do get some time, we can look
at it.
