Debugging the client on Linux

There's a problem with breakpoints and SDL under Linux. When a breakpoint pauses execution, the client keeps a lock on the mouse and keyboard (you can no longer do anything). If you kill the client process, you lose the breakpoint info. The current workaround is to call I_PauseMouse before any breakpoint you set.
