0.3.0: UDP Client/Server (#28)

* started work on UDP, will require more changes to the interfaces

* Deleted proj

* Renaming enums to the new lower-case convention

* Also fixing tests

* Giant refactoring WIP, changed abstractions, TCP and UDP need more separation than I previously anticipated

* Fixed adjusting of SocketConfig to the resolved address family

* Updated to Swift 3 Preview 1

* UDP Server and Client working!

* Finishing up UDP, tested for leaks and performance, all looks good
