7.x Structural Changes (#637)

* refactor(files): Initial commit on experimental file structure

* refactor(structure): New components system

* refactor(structure): Tidy settings' components

* Refactor(structure): Component exports and imports

* refactor(settings): Use new component imports

* feat: unified background.js script

* fix(build): Partially, distributions still not ready
