[Civil-devel]debug: show grid of hexes

[Marcus A. <maa...@ra...>]

duh, forgot to mention. Alt-G to enable/disable debug grid while 
playing.

You'll soon notice that not all hills are completely correct. 
Currently, hills are all on the "same height". This means that a hill 
hex which is mostly "high" still is considered the same height as a 
hill hex which is mostly "low". You'll notice this easiest if you pan 
along a hill-line, and press LMB. stdout gives the height of the hex.

If nobody understood the above, ignore.
