[Qt-creator] Editor improvements

[Adam Pawelec]

Hello,

I've got some ideas about editor improvements:
- duplicate current line (ie. by ctrl+shift+up/down)
- open new line after/before current (something like
Ctrl+Enter/Ctrl+Shift+Enter in Eclipse or O/o in Vim)
- auto add asterisk in multi-line comments (support for Doxygen will
be really great :))

And I've got a question - are you planning to add some refactorings
(implement method in source file, rename, create getters/setters) in
future releases?

Regard,
Adam Pawelec
