Trevor Parscal 735ed96f5f Add ve.Action, ve.ActionFactory, subclasses
Moved implementation of all the tools into a reusable action
system. To execute an action just call

surface.execute( actionName, method, param1, param2, ... );

This helps keep tools simple, and opens the door to key commands
reusing the same code.
