[L|0.1.334] middle mouse button without function

[foxbow]

Hello,

not sure if this is a bug and the search did not deliver any other result. On my Linux box the alpha runs fine but with one little thing. According to the docs, the map should scroll when I press the middle mouse button. However that doesn't work, the map is scrolling with the right mouse button. This would not be a big problem if that would not also mean that I was sending my drafted colonists anywhere just because I want to scroll the map. Using the mouse wheel to zoom works fine though.

And using WASD as a workaround is bothersome as I'm used to use the mouse for scrolling and WASD for moving.

Seen on Ubuntu 12.04 and 13.10
