[1/2] cmd: Add handler support for Ctrl-C and Ctrl-Break events

[Hugh McMaster]

Jason Edmeades and I have developed a patch that handles Ctrl-C and Ctrl-Break events in wineconsole's cmd.exe.

The patch supports interactive mode, batch contexts and both the cmd /c and cmd /k modes, meaning that pressing Ctrl-C no longer closes cmd.exe.

For loops, commands such as 'dir /s /w' and other such commands can be stopped. Batch scripts prompt the user whether the current batch execution should end.
