122x32 GLCD basic code

[skimask]

Wrote this code for a 122x32 graphic LCD, based on a SED1520 controller. (bought it at www.lcdmodkit.com)

Basic functionality, clear screen, x/y point set/reset, a few text functions with most of the visible ASCII set supported, and some of the non-visible characters changed to things like a full/half/empty battery indicator, bargraphs, and so on.
Works very well, as long as you've got a CLEAN 5v power supply. The LCD I've got doesn't like messy 5v, doesn't startup too well.

As with all things, Y.M.M.V.
