Add mimetype support for system testcases to qml editor

System test-cases are (assumed to be) written in javascript when using
an .qtt filename extension. These modificatons ensure that a js editor
is used whenever an attempt is made to open a file that ends with .qtt.

Also add support for recognising testcases to QmlOutlineModel.
