Subject: Added eeprom load/save API (no wear levelling yet), verified it works
in DarkHorse.

Subject: Made wear-levelling work. Takes a bunch of extra ROM though. Also,
I've only tested it a tiny amount.

Subject: Added option to start at memorized level, for momentary use on
dual-switch lights. Renamed WL versions of eeprom functions, for naming
consistency.

Subject: Made it possible to override address of eeprom array in RAM. (useful
when trying to use a single large data structure without wasting twice its
size in RAM)
