+15.05.2011:
+ - Changed mouse wheel behaviour in graphical editors except the score editor (rj)
+ * wheel scrolls left-right
+ * shift+wheel scrolls up-down
+ * control+wheel zooms horizontally
+ TODO:
+ - score editor
+ - zoom to where the mouse is located
14.05.2011:
- Fixed problem with project save dialog missing a forward slash '/'. (Tim)
