Initial checkin of a resource editor similar in style to QuickRes -- Resourcer's code is too difficult to maintain and the others on BeBits are either not good or the author could not be contacted.

This is currently a work-in-progress - right now it can only view resources and attributes.
Haiku target builds but R5 is broken because of a linking issue that will hopefully be resolved shortly.
