FishLight: Comment out the get_clk_status feature

Commenting out the get_clk_status feature for now because the hardware
is not up to snuff yet.  With the SQW pin connected, it seems to have a
really hard time functioning.  Once the hardware gets fixed, this code
may come back.
FishLight: Change the night brightness

Changing the night brightness to be much less bright.  The blue LEDs are
ridiculously intense.  So I am toning them down a bit.  Also, I am
adding a little bit of the Warm White because I think it makes it look
much more natural to not just be blue.  May change this to Cool White in
the future depending on how I like the warm white look.
FishLight: Rearrange setup function

Rearrange the setup function to be more intuitive and flow more
naturally.
FishLight: Add new RTC commands

Add functions RtcWrite, RtcRead, and getClkStatus to the time file.
These command can be used to write and read a specific register in the
RTC, and check the clk data pin.  The Write and Read functions need to
be updated to Write and Read more than one byte at a time because doing
it 1 byte at a time is slow and has lots of overhead.
FishLight: Add RTC SQW initialization to setup

Add an RTC write to init the square wave generator output on the RTC.
This should set it to output a 32.768kHz square wave.
FishLight: Add some debug messages

Adding debug messages (commented out for now) that are useful if the
program freezes to see where it froze.
FishLight: Add and remove some variables

Adding some variables for the RTC square wave output.  Also made some
#defines for the LCD screen.  Also moved some variables around.
FishLight: Add functions and support for debug

Added some functions for debug support such as debug_serial and _none,
and also added them to the existing functions as necessary.  Also add
commands to write and read bytes in the RTC.
FishLight: Updating cursors and main screen

Updated cursors to take advantage of the LCD #defines for its size.
This will make it easy to update the size if I want to get a new one.
Also added '<' and '>' to the main screen so I can add menu
functionality.  Moved the other display parts accordingly (for time,
brightness, etc so it all aligns).  I will need to move the select area
for changing the time using the buttons next to align to the new area.
Maybe this should be defined somewhere global.
