Manual input for simulation properties

[BEG5210]

An alternative to the sliders, where the user can instead input a number into a text box. its really finicky getting the exact value on a slider, and on my low end laptop it lags like crazy while i change the perameters, making it even harder to get the exact values that i want.

You could also take this a step furthur, and manually input values for the vertical, horisontal, and rotation of the light source, so you can get it exactly precise.
