Adding initial Teensy 3 support, compiles, but not fully functional yet.

- CDC Output seems to be working
- USB Keyboard output has not been tested, but is "ready"
- UART and Timers have not been tested, or fully utilized
- Issues using Timer 0
- Initial template for MBC-55X Scan module (only module currently compatible with the arm build)
- Updated the interface to the AVR usb module for symmetry with the ARM usb module
- Much gutting was done to the Teensy 3 usb keyboard module, though not in an ideal state yet

// USB Descriptors are binary data which the USB host reads to
// automatically detect a USB device's capabilities. The format
// and meaning of every field is documented in numerous USB
// standards. When working with USB descriptors, despite the
// complexity of the standards and poor writing quality in many
// of those documents, remember descriptors are nothing more
// than constant binary data that tells the USB host what the
// device can do. Computers will load drivers based on this data.
// Those drivers then communicate on the endpoints specified by
// the descriptors.
// To configure a new combination of interfaces or make minor
// changes to existing configuration (eg, change the name or ID
// numbers), usually you would edit "usb_desc.h". This file
// is meant to be configured by the header, so generally it is
// only edited to add completely new USB interfaces or features.
