Make Register16 a class, rather than struct. Tricky, but a bit faster than before.

Whoops: missed bus read/write clock ticks in the 6502 emulator.

Help out callers using Register16 arguments a little: Don't always require the ".Word" property to be passed.

Resurrect the Register16 class. This (or something *very* much like it) is going to be necessary to add a Z80 emulator (reference access to the high/low parts of 16-bit registers).

Not sure if this was a really good idea, but integrated StyleCop rules into the builds. Corrected all except documentation problems.

A few small consistency updates:
...
1) Drop Get/SetPagedByte in favour of normal BusRead/Write
2) Tidy some "using" statements
3) More "expression body" usage, if possible
4) Use field initialisation, rather than construction, if possible
5) Correct IntelProcessor register set/get methods (there were remnants of "copy pasta" code)

Drop Register16 support (replaced with explicit ushort), add some unit tests (Chip class only at present)
...
Now runs some instructions before going wrong...
