- removed _sharing_strategy and the methods that go with it, as its behavior is handled by the sessionEnabled() method

- added generic tunnel data item, along with item priority consts. Serialization still missing.
- added new class for turtle client services, and entry point methods.
- removed file name and file size ffrom _outgoing_file_hashes and _incoming_file_hashes. They are not needed.
- changed some names to more generic ones.
