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).
