remove unnecessary resources.hpp include from unit.hpp

It turned out that alot of compilation units were using resources
but not including the header, and only getting circuitously
through the display.hpp header which got it from unit.hpp. This
is an improvement since unit itself doesn't need the header,
and most classes probably don't either.
