Add: Ability to get uniforms from Shader.
Add: First steps to move landscape shaders to material
Merge branch 'development' into feature-landscape-material
Change: YamlNode objectMap is changed to multimap, because yaml support multimap items.

PLEASE BE CAREFULL THIS IS VERY IMPORTANT CHANGE, SO DOUBLE CHECK HOW DO U USE YamlNode.
It 99% cases it shoudn't create a problem, and just create a compilation error.

Very important that now you can use the following in your yaml configs:

node:
   input: [a, b, c]
   input: [b, c, d]
   input: [f, e, n]
   output: [b, e]
   output: [f, c]

So you can easily use multiple items in map with the same name.
