-												[qfcc] Support some unicode ops and GA ops

Only · (dot product) and × (cross product for vector, commutator product
for geometric algebra) have been tested so far, but that involved
fighting with cpp to get it to not convert the · to \U000000b7, which
was rather annoying.

-												[gamecode] Switch dot products to give a scalar

Making them give a vector was a mistake for Ruamoko. I've probably got a
mess to clean up in game-source, but oh well.
