Alters mapsymbol colors

Hoping to standardize 'em rather than just turn the dojo grey, but it turns out that we don't seem to have the full palette we have for critters.  So here's what I've got.
MA training (dojo/boxing) is inverted ltcyan; liquor stores are inverted magenta to distinguish them from bars & pizza parlors, which serve food & drink rather than just sell booze.

Let me know if you've any other ideas.
