Static Content API and the old school RESTCaller are obsolete with compiler error. From now the SenseNet.Client is V4.0 candidate (#146)

* reduce old RESTCaller calls

* Reduce old RESTCaller calls (remains 35/64)

* Reduce old RESTCaller calls (remains 5/64)

* Refactor SecurityManager and related items.

* Refactor TokenProvider & SecurityManager

* Reduce number of static Content API calls.

* Remove all obsolete calls of the static Content API.

* Fix tests (reamining: 2 red).

* Inactivate the test for "CertificateCustomValidationCallback".

* Fix ToContentEnumerable method.
