Added const where possible to the source functions in the Projects directory.

Added command timeout to the AVRISP project so that incorrectly connected targets no longer freeze the device.

Removed string descriptors from the TeensyHID bootloader to reduce its size.

*
* <b>New:</b>
* - Added TPI programming support for 6-pin ATTINY to the AVRISP programmer project
* - Added command timeout counter to the AVRISP project so that the device no longer freezes when incorrectly connected
* to a target
*
* <b>Changed:</b>
* - Slowed down bit-banged PDI programming in the AVRISP project slightly to prevent transmission errors
*
* <b>Fixed:</b>
