Split up 'Remote Sensor Closed Examples', add more Pigeon-integration examples

[ozrien]

The Remote Sensor Closed Loop examples demonstrates...

• Talon SRX / Victor SPX auxiliary closed looping on heading while closed looping pos/velocity/motionmagic
• Talon / Victor arbitrary feedforward for single-axis loops
• Talon / Victor aux heading closed loop via Motion Profile Arc
• Talon / Victor aux heading closed loop via Motion Profile Arc with feed forward
• Use of the remote sensor types (Pigeon IMU and remote Quadrature encoder)
• Use of sensor sum / sensor difference (for encoder-derived position and heading).

These examples should be broken out to several projects so that they can be found easier.
