Write the entirety of the Wiimote EEPROM, in a per-Wiimote file 

Previously, only Mii data was written.  Additionally, the file containing mii data was shared for all Wiimotes, which made it a lot less useful.

Additionally, the file was read/written on each Wiimote read, even though the whole EEPROM was kept in memory.  This was bad for performance and not particularly necessary (it did enforce that the data was properly shared between all Wiimotes, but that's not something I want).
