Title: Wrap pc around from 0xFFFF to 0x0000 on step and other pc++ operations

This will make the following instructions result in an infinite loop incrementing register A:

ADD A, 1
SET PC, 0xFFFF

Currently PC appears to wrap around after 0xFFFF, but actually increments beyond memory range and executes no operations.

There's also a commit to convert the remaining tab characters to spaces.
