Merged Harbors

Yet another remix for [Dakanzla](https://www.thingiverse.com/thing:2525047)'s excellent Catan-style boardgame. I merged the harbor parts with the standard sea tile. Off course I'm not the first one to have this idea ([Social](https://www.thingiverse.com/thing:3888985), [Jakwiebus](https://www.thingiverse.com/thing:3265702)), but I didn't like the gap between pier and water and the fact, that there are different waves under the ships.
I liked [hartk1213](https://www.thingiverse.com/thing:4227751)'s benchy idea so much, that I added one as well.
This version is intended for hand painting, so the potentially higher number of usable filaments from printing them in three parts, isn't needed.
