Updated DiStella disassembly to differentiate between the intent of an 

instruction (read vs. write) for those addresses that have different
meanings based on how they're accessed.  For now (and probably forever),
this only affects TIA addresses.

These ideas were ported from the old Stella disassembler.  Perhaps they
should be ported to distella as well, since it makes for more accurate
results.
