New module structure (refactoring)

* simple serializer and deserializer with models, new architecture
* move logic to strategies
* datetime strategy, some changes in order to make subtype parsing possible
* fallback to array casting for internal objects
* serializer now supports typed arrays and formatted DateTime
* models, prevent hangup from circular serialization of empty entities, improve compatibility with JMS Serializer (to simplify usage), (de)serialization callbacks
* fuser repository & correct annotations
* correct naming for proxy
* move several helper methods to the new structure
* customizable customer building
* more models, api corporate customer builder & bitrix customer builder
* AbstractApiModel shoudn't implement Traversable
* check if user exists in the order before building corporate customer
* don't check _rc cookie; it's untestable for now
* better structure + service locator, cookie extraction should be testable now
* enable forgotten domaincollector cookie extraction
* partial api client facade implementation (full implementation is not necessary for now)
* remove unimportant assert in tests, move utils to service
* move identifierspair to correct directory
* move CookieExtractor assert to a single test
* more models & ClientAdapter
* fix DateTimeConverter test compatibility with lower php versions
* update test date format
* finish customer-related methods in the client facade, fixes in models
* minor tweaks for (de)serializer, compatibility layer for models which implement types without full functionality
* make model's getters nullable
* better logic for AbstractSerializableModel
* different logic for AbstractSerializableModel
* ability to create filled AbstractSerializableModel by passing primary key value
* reuse logic from repositories for passing primary as constructor parameter for AbstractSerializableModel
