Merge pull request #7 from nicksi/master

New function to draw and fill polygons
moved PolyFill enum to its own file, updated sample to match
removed static keyword, drawing is typically done on instances
lots of bluetooth support added for AGENT and WP8.  I created a simplistic way to work with SerialPorts and Sockets on both sides of things, and abstracted ways for dealing with the raw data over the channel
