Cleanflight Fork

Finally had time to create a github project for CleanFlight fork.  Over the next few weeks will post changes to allow CleanFlight to compile on Linux . 

There are a couple targets:

• PC - Allows CleanFlight to run on a PC and connect to a I/O processor
• Helps in debugging and test with CleanFlight configurator
• PI Zero
• Connected a powered USB hub to the PI
• Connected WIFI dongle
• Connect I/O processor
• Orange PI
• Still working/waiting for some fixes to mainline, but will push forward with the basic camera.

Right now, working on creating a I/O processor board.  This will be a simple perf board wired up by hand.  The reason for doing this, simple and cheap.  The following sensors will be supported

• GPS
• Compass
• PWM In for RC
• PWM out to motors
•  USB

The board for the PI Zero will also be a perf board.  But, it will use machine pin headers to keep the profile low.  This board will have just two sensors:

• 9255 (IMU)
• MS5611 (GY-63) 
• Headers for motors
