change behaviour of underwaterOnly to land, water or neither (modder feature)

[kikimoristan]

I think I may have requested this previously. I am not sure. I apologize in advance if I did.

The only thing I can think of is

underwaterOnly: 0 1 2

0 = everywhere
1 = underwater only
2 = land only

This is a quick and dirty change to allow modders to restrict equipment both ways and still be compatible with anything out there.

Yes, please. I have so many plans for this.
