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

[Claudio L.]

It's ROM update time.

This one brings:
* Fixed the IP command bug
* Added SQ, LOG and ALOG commands
* Bound 10^X, LOG, LN, EXP, SQ, XROOT to the corresponding keys
* Implemented new menu framework (not visible to the users).

For now, the first menu is also VARS, simply because for the time being there's no other menu to show.
