Get it finally working (somehow)

Browse Source 
- Add working example
- Add Namespace defs for Iron Ctr and C3D
- Add Exit func / Vertex / Index counter to Iron
- Add format bytes function to utils
- Make stb_image optional
- Compute texture uv's
- Clear Everything in Drawlist::Clear
- Use Amy::mat4 as matrix lib
- Fix the most stupid rendering bug (i -> m_idx)
