Enforce Abstract

making abstract classes and interfaces inherit from abc:

• would prevent to initialize an instance of an abstract class
• would prevent to initialize a class without having overwritten all the abstract methods

Looks reasonable to me! @vilim? @diegoasua?

Love this consistency. Clear and strong 👍 . Just remember to lint it before merging and good to go

Thanks for the approval @diegoasua @vigji !
Unfortunately it's still in progress, i need to finish changing a couple of files.

Sorry if it wasn't clear from the description
