Updated EEPROM storage class

Browse Source 
To avoid having a .cpp just for an extern variable definition, `static`
has been chosen over `extern`.

As the `EEPROMClass` class simply wraps functionality located elsewhere,
it is completely compiled away. Even though each translation unit which
includes the header will get a copy with internal linkage, there is no
associated overhead.
