Removed the hintPicture from FilenameLayoutDialog.
I think most of us agree that the hint picture was too empty and to thick. However I feel that by removing it the dialog's workflow structure suffers greatly.

At the moment I see 4 alternatives:
1) Readd the hintPicture and superimpose some hint text.
2) Readd the hintPicture and only center the icon, maybe make it thinner.
3) Leave it as it is, without any hint picture, I'm against this.
4) Add the icon from hintPicture to the FilenameLayoutWidget itself, right before the "Drop tokens here..." text.

Please review this and let me know what you think about it.
