Add SimplexNoise and NoiseTexture as new resources

Browse source 
SimplexNoise can be used to generate parameterized fractal noise based on Open Simplex.

NoiseTexture uses SimplexNoise to generate noise textures for using in
shaders/visual effects.

<brief_description>
[SimplexNoise] filled texture.
</brief_description>
<description>
Uses a [SimplexNoise] to fill the texture data. You can specify the texture size but keep in mind that larger textures will take longer to generate and seamless noise only works with square sized textures.
NoiseTexture can also generate normalmap textures.

If true, the resulting texture contains a normal map created from the original noise interpreted as a bump map.

Whether the texture can be tiled without visible seams or not. Seamless textures take longer to generate.
