[Development] Exposing QMimeDatabase to QML; QtQml.Utils?

[Alberto Mardegan]

Hi all,
  in addition to making QMimeType usable from QML [1], jpnurmi also
suggested of exposing QMimeDatabase as a singleton.

The open question is where this element should be added: I suggested
QtQtml.Models, given that it's a database, but maybe creating a separate
module QtQml.Utils might be a better idea?

If so, do you have suggestions for other classes to be exposed by it?

Ciao,
  Alberto
