Change Apio branding to Apio Core and Apio IDE (similar to platformio).

[zapta]

This issue is to brand Apio similar to Platformio as having two tracks Apio Core (command line) and Apio IDE (VSCode extension). This new 'branding' will help new users to choose the track that fits their needs, and like platformio, Apio IDE is built on top of Apio Core and installs it as well.

This change will affect the Apio's documentation, the actual code and build workflow already follow this model.

.. we can also have IceStudio under this branding as Apio GUI or Apio Designer. That is, three levels of user interfaces (command line, IDE, graphical designer) with a common underlying functionality.

@cavearr, this is food for thought, maybe one day, down the road. ;-)

Hi @zapta! this is on my radar , the same as visualstudio plugin, i'm working on it in the new version ;)

Here are the relationships between the three components. The installation of each component is independent and includes all of its dependencies.

Updated the docs. It's good enough for now. Closing.
