Simplifying The Test UI

I have temporarily disabled the test UI that allowed users to tweak numbers. Later today I will upload a new version that has a more focused set of values to change. Including a gravity slider, jump release gravity slider (how quickly we zero out the y value), a 'fall weight' slider, and 2 toggles for linear movement in the air and on the ground.

Slopes have temporarily been removed so people can focus on trying the other aspects of the movement script. Once the more obvious quirks of my slope movement have been worked out I will re introduce them in a 'slope arena' section of the map.

HUGE thank you to everyone who has tried out the test build. Shoutout to MashedPotatoes, Mirzabeig and my friends that have provided feedback that is already in or making its way into the prototype!
