Set JSIL back to latest version
Fixed Example, removed unused project
Removed/Fixed #version120 in some examples and shaders
Fixed/Improved float3.Normalize()

float3.Normalize returns the given vector if its length is zero (aka
null vector)
Optimized float4x4.LookAt()

Using a method provided in the DirectX documentation. Probably a bit
faster than what we had.
Meh. JSIL doesn't like IsPositiveInfinity.

Replaced it with a Zero check. We should replace that with some epsilon
soon.
Merge remote-tracking branch 'remotes/origin/develop' into SceneManagement
Added new Diffuse Shader to MoreShaders.cs
