Map control

Right now the mouswheel scrolls the map up and down and together with Ctrl it zooms in and out. For two reasons I'd like this be be switched:

1) RTS standard: Every RTS game with a zooming map uses the mousewheel for zooming without any other key beying pressed. So that behaviour is more or less standard and expected by the player.

2) The up and down scrolling by mousewheel isn't really that usefull because you can only do vertical movements. Zooming on the other hand is being used constantly. Therefore the action that is being used more often should get the "easier" command.

3) I only even thought about using the Ctrl key for zooming in and out because my experience with Adobe products. You can't expect that from everyone :)
