Update 0.9.16

[h3]Bugfixes:[/h3]

• Fixed a recursion in the latest compatability patch for the 1.0 save file structure that lead to center skilltree node be replaced by a random skillnode. This resulted in one additional random skillnode getting added to your build on each map load/scene switch. This also resulted in showing the message that you do not have enough resources to attack as the additional skill node added some additional resource cost.
