Show QML files under "sources" and not "other files"

Hello,

Now that qml is becoming THE next big thing for Qt, it would be very nice to see qml files under the "Sources" folder of QtCreator, and not under "Other files"

Rationale #1: we have a lot of cpp files working together with qml files. We put the .cpp and the .qml under the same physical folder, to keep them close. But Qt Creator breaks this organization by displaying qml files under "other files" and forces us to scroll up and down the list to switch between them.

Rationale #2: QML files are source code files, and are first-class citizens in Qt Creator. They should not be relegated to a "misc." category

At least, it would be nice to have the option to set the filters that define what goes under source and what goes under "other files"

Thanks
