diff main/MainWindow.cpp @ 116:99d65ba33c88

* More useful status bar text -- show the current play time and the extents of
  the visible area
* Add update-i18n.sh to update the i18n/ts and qm files -- I can't get qmake
  to do the right thing now that the project file has been split up into
  several project files
* Fix missing Q_OBJECTs, etc, reported by lupdate
* Update Russian translation from AlexandrE
