Newly created QML files in existing projects have static version numbers of imported modules (different from the project's).

When creating new QML files (File > New File Or Project > Qt > QML File (Qt Quick 2)), the default first line is "import QtQuick 2.0", which in most cases differs from the rest of the project.

This easily leads to problems/irritations (if not manually corrected), and AFAIR even runtime issues when mixing module versions.
