Torbjörn Andersson c5978208f7 Allow the BASS debugger to be invoked by the "standard" Ctrl-D / ~ / # 
keys, since ` is bloody awkward on a Swedish keyboard. To keep joostp
happy, ` will still work even if it currently doesn't for any of the other
debug consoles in ScummVM.

/*
At the beginning the reverse engineers were happy, and did rejoice at
their task, for the engine before them did shineth and was full of
promise. But then they did look closer and see'th the aweful truth;
it's code was assembly and messy (rareth was its comments). And so large
were it's includes that did at first seem small; queereth also was its
compact(s). Then they did findeth another version, and this was slightly
different from the first. Then a third, and this was different again.
All different, but not really better, for all were not really compatible.
But, eventually, it did come to pass that Steel Sky was implemented on
a modern platform. And the programmers looked and saw that it was indeed a
miracle. But they were not joyous and instead did weep for nobody knew
just what had been done. Except people who read the source. Hello.
With apologies to the CD32 SteelSky file.
