Features:
- Added the "slobbery things" dev-sandbox to the game. This sandbox is featuring everything fluid related and will be further improved in the course of the next couple of days.

Controls: Pretty much like the gallery and the character selection of FeralIsland. You can hover with WASD and rotate with the mouse. VR is currently not supported but I think about adding VR support once the drippy fluid sim for the breeding-device is added. Shift: Lets the felkin sprint. Successfully implemented fluid systems will be added to the core game.

- It is now possible again to use numeric shortcuts[0 - 5] to navigate through the main menu.
