When multiple cut commands were issued, the cut command handler would
restart multiple times and keep running until the handler that was
invoked first finishes. As all handlers kept a selection copy, they
would try to save the deleted items to the clipboard resulting in a
crash.

- added selection of reference point
- added snapping when pasting
- some minor code refactoring
- disabled pasting between footprint and pcb editors due to model incompatibility
- added TOOL_INTERACTIVE::resetTransitions()
- made protected and moved TOOL_BASE::setTransitions() to TOOL_INTERACTIVE
- TOOL_MANAGER calls TOOL_INTERACTIVE::resetTransitions() instead of
setTransitions()
Some grid/zoom tools are left in PCBNEW_CONTROL because they currently
depend on Pcbnew-specific class members. Once refactoring is done to
make it possible to use all zoom and grid controls outside of pcbnew,
these last tools can be moved to common to match their ACTIONs.
New virtual class ACTIONS is added as a member to EDA_DRAW_FRAME so
that the TOOL_DISPATCHER can have access to the appropriate derived
version of TranslateLegacyId()
