Add line wrapping and support for arbitrarily long messages

Add trivial line wrapping algorithm. Words are only added to
a line if they don't put it over the column limit, and only broken if
they alone exceed the column limit.

Extend board size to 16x6, using 145 bits of parameter memory.

Add simple generate.sh script, which generates everything needed to
use the text-to-text board.
