ctrl-c on debugger

[Eric Pouech]

Ctrl-C on debugger console was no longer working because the i386 signal 
handler had been changed to generate EXCEPTION_SINGLE_STEP exception 
after DebugBreakProcess, whereas Win32 API requires an EXCEPTION_BREAKPOINT
this patch takes care of this (and ctrl-c on debugger reworked again)

A+
