Make .qrc files expandable in sidebar, and their files openable

In Qt Creator's Projects view in the sidebar, .qrc files show up as leaves in the tree, and cannot be expanded.
However, they contain groups of files in a hierarchy, and so it would be convenient to be able to expand them, and double-click files to edit them.
For instance, if I have a .qrc with a bunch of HTML help files, I might like to see the list and double-click one to open it in Qt Creator's text editor.
Right now, even if I open the .qrc file by double-clicking it, I still can't open any of the files in it by double-clicking on them, so you can count that feature request as part of this issue also.
