Log message

completely redesigned/coded handling of tab movement & re-grouping - it's all a
lot more awesome now (and important features will be much easier to implement)
fixed an accidental bug I caused, getRealHost() is more robust & clear,
refactored & clarified sorting mechanism, added lots of code for a new function,
see notes @ checkGroupLiteralGroup(), made a getPerceivedHost()

(I think I overdid it for a single commit, blah)
