Ensures all parts of the Electron have a fully-defined initial state.

Similar fix to that over in Oric land: ensure a known, effective initial value for the Plus 3's control register.

It would appear the 1770 and 1773 actually differ in relation to the (non-sensical) ability not to spin-up for a Type 2, and whether a side compare can occur. So the WD1770 class now requires a personality to be specified. Which it singly fails to honour.

Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register.
