Subject: [PATCH] clean up library view

library view sorts the library and display the contents in alphabetical order (bold letter/number followed by a line) . the line cannot be themed as it is hard-coded "QPen line_pen(opt.palette.color(QPalette::Dark))". Here i try to remove the line, align the letter to left and give the letter a highlight using QRect. this way it looks better and is completely themable ...
