Reorganize almost all Framework namespaces

[caendesilva]

An incredibly breaking pull request, as it modifies literally every single Framework file, and changes the namespaces for half of them.

I do feel like this is the time to do stuff like this, since next release is v1.0, and it's now or never. Hopefully these breaking changes will lead to better stability and maintainability in the future.

This would likely solve the sentiment of, and fix #592, and likewise fix #579
