Add support for ANSI escape sequence for saving the current location of
the cursor "\e[s" and for recalling the last saved location "\e[u".
Note: if no location had been saved yet and the restore cursor
position (RPC) ANSI escape is received, defaults to 1,1 (top left of the
screen).

Fixed ansii parsing (some issues still remain), and tested cursor
movement functions, though they don't seem to work properly through
serial yet. Also now when '\e' is read through serial, pause and
accumulate a the possible ansi escape to send to writeStringToLCD.

There are a few things that still need to be commented, furthermore,
usage of the library needs to be explained in more detail. Also things
are still somewhat unorganized as the lcdLib library is packaged up with
the lcdOutput application for testing. Also a tiny USART library is
included but has nothing to do with the lcdLib except that its used by
the lcdOutput demo program. When the lcdLib library is ready it will be
split into its own repository with accompanying examples (one of which
may be the USART echo example (lcdOutput.c as of this commit).

At some point perhaps switch to using doxygen to output nice
documentation. This will require using doxygen conventions, which aren't
currently used but easily adapted to.

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).
