Change Object Selection for Water and Park Entrance to Bullet Points

[733737]

I am creating this discussion to remind the developers of my desire to have bullet points available in the OpenRct2 interface. Currently they are not implemented. Specifically this would be most useful for color palettes. Some discussion also mentioned Park Entrances. I made an experimental PR that disabled the check for active palettes, but it wasn't something that was up to par with the standards of the project.
