v0.9.34 beta 9

Hotfix for beta 8.

• The game window now has the Lantern Engine icon too.
• Mouse buttons fixed: the engine counts middle click as button 2 and right click as button 3, but the defaults were written the other way round. By default, middle click now locks on and right click does the strong attack; firearm/parry is on right click and transform on middle click. If you never changed those binds, they're fixed for you on the first start. If you set your own, they stay as they are.
• The in-game controls page and the mouse button icons now show the right buttons.
