VERSION 4.12: post rendering effects and experimental WebGl export

It has been a while, but I was really busy. With the current update there come two major two things:
- post rendering effects, which is a separate shader pass to apply typical balancing effects, color grading effects (for example, to turn your artworks into "Matrix style"), Vignette and other effects
- experimental WebGl export: this allows you to export your current scene to be rendered in a modern browser in realtime. This feature is very limited in terms of supported features, but may be lead to very cool results, though. The more simple your scene is, the better it will work. The render results are similar to the "Realtime shader" when rendering an animation, but be really realtime. The motion of motion curves will also be baked in the exported data as well as an audio file, if specified.
But, be warned: especially on Windows it takes really a lot of time to compile such a WebGl shader for the first time, but then usually runs fine. So please be patient.
