* Moved Common::Debuggger to GUI::Debugger (mainly to satisfy linker
restrictions)
* Change the base Debugger class to *not* be a template class anymore;
instead, a thin (template based) wrapper class is used to hook up
debugger commands
* Removed duplicate Cmd_Exit and Cmd_Help methods in favor of a single
version of each in GUI::Debugger
* New Cmd_Help doesn't word wrap after 39/78 chars, but rather queries
the console to determine when to wrap
* Debugger::preEnter and postEnter aren't pure virtual anymore

Also now these special engine debug flags can be specified from the commandline.
Also made the -c & --config parameter check more secure.
