Improve performance when rendering map overlay texts

Browse source 
The text color was previously set and reset for every individual number being rendered for non-empty tele, speedup, switch and tune tiles. The color is the same for all tiles from each entities layer, so most of these `TextColor` calls are unnecessary. Now the text color is only set and reset once when rendering each entities layer.
