[REG 4.2 -> 4.3] Resource files treated as folders in Projects view

1. Have a source checkout of Qt Creator v4.2.2.
2. Open the project file qtcreator.pro in Creator.
3. Wait for project parsing to finish.
4. Show the Projects view.
5. Expand qtcreator / share / static / Sources / qml\qmlpuppet.
   You'll see a couple of directories and between the directories qmlprivategate and types, there's the file qmlpuppet.qrc.

Does it make sense to treat resource files as folder because they contain other files? If not, they should be listed among files, not folders.
