Collin J. Doering abacb2b30a Take screen characteristics into account
The writeStringtoLCD function now wraps text correctly and proceeds to
the next line when '\n' is reached in its argument.

Note: during debugging of this feature it was noticed that the function
loop_until_LCD_BF_clear is broken, as previously suspected. This forces
delays to be placed in the clearDisplay and returnHome functions and
could cause other undefined behavior if timing requirements aren't met.
