implement doctrine annotations in a rough way

proof of concept, did not work, performance is worse
Merge branch 'master' into doctrine_annotations

Conflicts:
	src/TwentyFifth/Serializing/Serializer.php
refactor everything

start making things right, still need to refactor Serializer and Doctrine Annotations FileCache
refactor Serializer, remove static calls

Introduce new Directory Doctrine to keep things together
Remove hardcoded cache
Introduce some Interfaces
introduce differentiating in serializing a list
let child objects override their parents
Introduce SerializableMethod instead of CallableMethod

remove concern about specific project case, all we have to do is serialize, nothing more

also introduce 'has' getter possibility
add missing namespace, bump lock file
adjust tests to changes
