Patch v9.19

* Made leaf models with even fewer polygons, which should greatly increase the frames per second (= a smoother experience)
* Removed a lot of invisible polygons from the sandbox terrain, which should greatly increase the frames per second
* Changed the prebuilt organism library to somewhere which is always outside the camera frustrum, so it's not 'considered' for drawing and animating, which should greatly increase the frames per second
* The game now reuses procedural materials whenever possible, so the GPU has less work to do (more FPS) and the game needs less RAM
* Added various question mark tooltips to the editors
* Fixed the render distance for babies
* Fixed crash/glitches after loading savegames with instincts
* Fixed 'feel' instincts being saved incorrectly in a savegame file
* Fixed scenario redirection after loading and then winning a scenario
* Player edited soil and family relations are now also stored in a savegame file
* Stopped optimization technique that fakes models that are not ready yet from also being used in the desert level
* Toned down the sun shaft eye candy during some times in the day night cycle
* Recolored the 'eats meat' icon
* Small improvements to where plants can grow for the sandbox and flower level
