v3.0.0

In the new version, we've improved every module and done a lot of work to ensure everything inside the Superkube is well-organized, consistent, and as reliable as possible.

So every module and almost every detail has been improved. But in general, the framework is compatible with the previous major version, except for renaming some modifiers of modules and utilities such as border, radius, shadow, etc.

So, finally, by the third version, we managed to make an almost perfect SCSS/HTML framework, most likely the best in the world today. There is a lot of work ahead to create examples and all sorts of other valuable things with explanation and demonstration of all the power of Superkube.
