Develop

Key goals:

* Interface for common/same method names.
* Clean branch working with master and develop branch.
* Start using (CakePHP internal) semvar from here on and release more frequently.

Also:

* Upgrade to current CS and guidelines/conventions (2.5)
* Check against CakePHP2.6 as well.

I can add an overview of available languages + methods in the wiki here.
And also release tag 2.2.0 soon after with the (fully BC) changes included with these latest commits.

Soon after we can start migrating it to a first Cake3.x ready plugin in a new "cake3" branch and remove the deprecations along with it.
