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.

Removed the repeated #defines for LCD_DBUS*[,_PORT,_DDR,_PIN] used for
both FOUR_BIT_MODE and EIGHT_BIT_ARBITRARY_PIN_MODE.

After trying FOUR_BIT_MODE to ensure it worked properly, forgot to
comment it out so that the default mode is enabled as expected and
documented.

Tested mode 1 (default 8-bit mode), and mode 2 (8-bit mode with
arbitrary pins for the data lines).
Signed-off-by: Collin J. Doering <collin.doering@rekahsoft.ca>
1. Default mode (8-bit data bus, control lines on any PINs)
2. 8-bit arbitrary pin mode (8-bit data bus on any PIN, control lines on
any PINs)
3. 4-bit mode (4-bit data bus, control lines on any PINs)
Default mode is tested and working. The others still require testing.
