Debugger: Mute sound when entering debugger from MODE_STEPPING:

Browse Source 
. ie: ESC, F7 and Pause key
Debugger: Fix for MODE_STEPPING when jump from $C3xx to $C8xx:
. Don't break on floating-bus, as Expansion ROM will be switched in on
this access.
IORead_Cxxx(): Fix the logic for IO_SELECT when not slot-3
