This patch adds support for the 16x2 LCD screen on Ben Eater's 6502 Breadboard Computer.

C code to drive the LCD via PORTB on the 6522 VIA.
Declarations in eater.h for programs to use it.
Example scrolling text marquee program.

llvm-mos generated better driver code from lcd.c than I could have achieved in hand-crafted assembler! So that was a welcome surprise.
