PICO-8 size optimization stuff

Here are some simple ways to make your PICO-8 code fit in 140 characters (as in the tweetjam 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

Patches to skip the splashscreen and logo/version display when the PICO-8 editor starts. Intended for development purpose only.

Please check the thread: https://www.lexaloffle.com/bbs/?tid=3485. It contains instructions on how to reproduce the patch for different versions and OSes.

Download one of the patches below matching your PICO-8 version, then patch your binary.

At first I didn't manage to upload binaries as raw gists, so I pasted binary dumps instead so you could convert them back to binaries with xxd reverse dump operation xxd -r my.patch.txt > my.patch.

But I managed to upload the binaries by cloning the repo and pushing the new files back, so now both the dump and raw versions of the patches are available.
