Well, a little. At least one person can now run Gallery.qml again.

Removes all menu related stuff, removes Window (uses the
Window in QtQuick.Window instead, despite reduced functionality now).

Updates to work with the quick module split, and the xmllistmodel
module split.

Updates version number to 0.2 as well.

We need this for SplitterRow and it has been released for a
while.

For some strange reason, all menues stopped working after we moved
to installing desktop components under QtDesktop. So to solve this
problem, I rewrote the way we decalre MenuItem to be purly QML
based, and not c++
