newRPL: [UPDATED April 27-2017] Firmware for testing available for download

[Han]

Some quick notes:

1. [[1 2 3][0 1 3][2 4 6]] RREF complains of a bad opcode
2. long-press HIST for PURGE and short-press HIST for STO seems like a bad combination for accidental deletion. I recommend forcing a shift key for PURGE and having long-press show the variable menu or perhaps later on showing the history of commands once that feature gets implemented (or will it be?)
