Subject: Some cleanup for the script debugger code: - Renamed struct
 DebugState to ScriptState and r_amp_rest to restAdjust inside EngineState.
 Changed restAdjust to be a uint16 (actually it is a uint16, but it was being
 casted back and forth from an unsigned integer, so this clears up its type
 and size) - Moved the script state variables from inside the run_vm() into
 the ScriptState struct, so that they can be accessed by the console commands
 and the script debugger all the time, and removed the weird isValid code
