[Qt-creator] Open documents related.

[Paulo Jnkml]

Hi,
just compiled the main git branch.

I noticed that there was an attempt to correct the double click need in 
the open files view.
Unfortunately now not only it doesn't open with a single click but it 
also doesn't open with any number of clicks.

I asked the people on the qt-interest list, if it was possible to set 
the color individually on a QTreeView.

I was thinking it would be nice to get a visual hint, like the open file 
name turning blue, and getting the typical filename* when modified.
All in the Project files view. That way I would avoid the open docs view.
Another nice thing would be for a single click on a blue (open) file, in 
the project view, would also switch to that file on the current window.

How about that?

=)
