Made the kyra debug extensions more generic, i.e. scumm engine could replace

their debugC calls now with the new introduced debugC calls.
(A mail how to use it will follow shortly on -devel)
Also now these special engine debug flags can be specified from the commandline.
Also made the -c & --config parameter check more secure.
