Temporarily halting development

[XavierCS-dev]

I have taken the decision to temporarily halt the development of this engine.

As much as I love Rust, the graphics ecosystem is a huge nightmare, with everything depending on each other, with constant breaking changes and very opinionated libraries which are not fun to use as they dictate the structure of the entire project.

I am currently in the process of learning Vulkan and improving my knowledge of modern C++ and will eventually switch to that for the renderer, GUI and core engine components. The rest of the engine, including future networking will hopefully be in Rust, and I will provide Rust bindings for the core engine components.
