Improvements to the title editor

I think there is room for some improvements in the title editor. As it is now, only the image edges are marked, and the aspect ratio is always 4:3. There should be a marking for the title safe area, and the image aspect ratio should be automatically selected 4:3 or 16:9 based on the current profile. This would make title creation much easier. Also on the wishlist, but not as important: For titles with more than one line it would be nice to have the ability to have different font/size/color on each line without going to "Advanced" and open Inkscape.
