Islands up for grabs, WIP 2

Islands!
Phew, after almost no work at all yesterday (family vacation) I’m now progressing. There might actually be a game in there somewhere. Got a nasty problem yesterday where the compiler wouldn’t let me compare a const std::string& with a string literal. Took almost half an hour to figure out that was not included.
Anyhow, you can move, chop trees, build boats, claim land and the AI can do most of that as well. It’s just not particularely smart about it
Quite a few impressive WIPs to be seen, hope y’all don’t forget the gameplay!
