1.0.5 - Improvements for 412, 212, 402, 202

With the recent update to the datasheets, it was revealed that there were additional PWM outputs and options for UART pin mappings available on the 8-pin parts that were not listed in the previous version of the datasheet. This update adds an option to use either UART pin mapping, and adds PWM on pins 1, 2, and 3.

This is the version for board manager installation.
