More crimes against version control.  Added command line flags for --length indicating the number of LEDS in the string, and a--type indicating the driver to be used.  Added support for the lpd6803 LED driver.  Added a number of request handlers for relaying event status back to the ui.  Implemented a 'cycle' mode which uses interval events to cycle through the entire colour wheel over the course of 40 seconds.
Update README.md

Added argument syntax to readme, although it can be found with app.py --help
