Collin J. Doering 435c8eb07b Fixed busy flag check 
Inspired by
http://web.alfredstate.edu/weimandn/programming/lcd/ATmega328/LCD_code_index.html.
Forgot about the 'data hold time', 'address hold time' and 'enable cycle
time'. These delays should eventually be implemented as preprocessor constants.

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.
