Release v2.0.0-rc3

This is meant to be the last RC but a wise man said not mention that. Well... it's done now...

The plan is to let this go for a week at least and then tag it 2.0.0 (finally). After that the focus will be on bringing projects alongside Joken like joken-plug, joken-crypto and so on...

New

• Project moved to joken-elixir organization as we plan to add other dependencies here related to joken;

Backwards incompatible changes with previous RCs

• Hooks were 100% re-implemented. The first shot of hooks was a complete mess. This excluded something around 180 source code lines but introduced different function signatures. To make it more consistent, they all follow a before_ or after_ signature. Please, refer to the docs of the Joken.Hooks module. Also the typespecs are now accurate.

Fixed/Added

• Refactored typespecs to be consistent (should warn a lot less now and dialyzer passes 100% - initial contribution by @chulkilee);
• Made order of arguments consistent now (a problem highlighted by @ajkeys and fixed by both of us);
