core: bridge selection + improvments for android
    - bridge specified in sat.conf is now imported, in the same way as for backend
    - when loading, a label showing "Loading please wait" is shown
    - postInit is now call when backend is ready
    - avoid division by zero when icon is not available in cagou_widget.kv
    - twisted reactor is used
