(MESS) nes.c: slightly more refined open bus emulation (still not 100% accurate, but it suffices
to make happy the two games which had issues with previous implementation). nw

Adds memory tracking to debugger.  This includes two new commands:  trackmem and
pcatmem(p|d|i).  [Andrew Gardner]

Fixes left-click selection bug in the memory window. [Andrew Gardner]


Explanation:
------------
Call trackmem to start tracking which PC writes to which address in memory and 
pcatmem(p|d|i) to query a memory region for which PC wrote to it.  Users of 
the QT debugger can also right click on a memory address in the memory window 
to make a popup message appear with the results - right-clicking also 
automatically copies the resultant PC onto the clipboard.  (I'll attach an 
image of this behavior in a follow-up mail).
