Procedures for writing to LCD

After some trial and error, writing to line and to 8 segments in a line
is possible.

The only thing left is to get some params together :)
Hot fresh text inputs straight to LCD

The liquid crystals on your Push's text display are yours to patch.

Each line can take 68 characters. It probably won't work if you send it
more.

NOTE: The 'LCD 8' segment inputs are not yet ready, these will be
commatext and should make setting up some generic CC send patches easy
as pie.
