Merge pull request #1 from nathanielatom/master

Deserializer testing complete
Deserializer finalized

Removed debugging parameters from the Deserializer
Serializer Start

Changed the AquaTux SPI documentation; added a rough draft of the
Serializer.
Serializer Round One Done - Testing needed

Created a serializer and a shift register for it. Needs testing.
Serializer - Round Two | SPI - Round Four

Made the SS output be clocked by a clock cycle; added a timer to the
serializer; made MOSI be tri-stated.
Modified AquaTux Master

Forgot that MDA code assumes async.
Serializer - Edits

Realized that I was sending out the wrong wire out of the serializer -
we want to send out the fact that we're in the sending state, not that
we're done. Also realized that counter_start is when we are in state
SEND, or 11.
