* Implement a load values from accessor function.
Added some more value types for the different GLTF attributes.
Fixed crash when loading animated triangle.

* Split GLTF model loading into separate functions for readability.

* Fixed the already working models that I broke when introducing GLTFReadValue.
Improved the example for gltf models to be able to switch between a few models.

* Removed license from screen. It is pu inside a license file anyway.

* Small improvements on the naming of functions
Removed (*model). and replaced it with model->

Some enums values have been renamed to be more consistent and also provide a more detailed description:
 - ShaderLocationIndex:    LOC_VERTEX_POSITION -> SHADER_SHADER_LOC_VERTEX_POSITION
 - ShaderUniformDataType:  UNIFORM_VEC2 -> SHADER_UNIFORM_VEC2
 - MaterialMapType: MAP_ALBEDO -> MATERIAL_MAP_ALBEDO
 - PixelFormat: UNCOMPRESSED_GRAYSCALE -> PIXELFORMAT_UNCOMPRESSED_GRAYSCALE

* Added bone binding to whole mesh and not only set vertices.
+ Also added missed setting of the animation count.
+ Removed double ; on one line

* Added more of the gltf sample models

https://github.com/KhronosGroup/glTF-Sample-Models
We need to make it working for all of them.

* Binding to initial bind pose added.

* Fix cube disappearing bug because lerpPercent could be Inf.

* Fixed for rigged figure also

This is to account for GLTF info being more like instructions on how to build your animation instead of verbose description of each pose.

* Added example for gltf animation and split some functions for loading model animations into IQM and GLTF similar to how models are being loaded.

* Removed wrongly duplicated function

* Bone loading for gltf model (not working at this point)

* Loading info about vertex to joint connection but animation is still not working

* Skeleton and pose is correctly loaded. Need to communicate about interpolation in GLTF

* The model almost looks like a real person on animation.

* Fixed model loading with bones.

Also updated license info on the model.

* Cleaned up some code and updated examples.

* Fix identation issues
