Log Message:
-----------
Add 'cut-through' option for Knife Project operator.

If enabled, it makes knife project act as the
cut-through (Shift-K) version of knife.
This option will soon be more useful when a better
cut-though Knife change is submitted, allowing
this to work for cuts within faces in addition
to cuts across them.
