Do something about tolerances when needing to switch patch on patch extinction

[hhyyrylainen]

as otherwise the player might get a cascading series of extinctions if they are no longer adapted to the previous patches they can go back to

One solution I see is giving the player basically a free tolerances change if they are no longer adapted to the patch they go to (it should be relatively easy to just use the same method as is used for setting up species initially for tolerances).
