[Development] Wither QString?

[Henry Skoglund]

Thanks for the answers!
I haven't got much experience yet of std::string so I thought the grass 
was greener over there. But sure, functions like split() and trimmed() I 
use regularly, and they indeed seem to be lacking in std::string.
So sorry QString about that brief moment of infidelity, won't happen 
again :-)
