Add memory contents to "Addr=" string in debugger

Browse source 
Tweaks the format of the addr= string in the debugger/trace so that it includes the memory contents.
It will also take the 2nd character of the opcode and if it's b or h it will size it accordingly.
so
addr=800BC2D0
becomes
addr=800BC2D0[00000000]  or addr=800BC2D0[0000]  or addr=800BC2D0[00]

This change amongst other things will facilitate a widescreen cheat scanner, that will take a lot of the work away from making widescreen cheats.
