Trying to use Boost ASIO endpoints for IPv6.
Bind IPv6 addresses only.
Drop an unneeded CMake flag.
Merge branch 'master' into boost-asio-endpoints

Conflicts:
	include/cocaine/asio/local.hpp
	include/cocaine/asio/tcp.hpp
	include/cocaine/asio/udp.hpp
	src/app.cpp
	src/context.cpp
	src/locator.cpp
Use ASIO resolver instead of my own crippled one.
Minor code beautifulization.
Properly handle resolver errors.
Try every possible endpoint when adding a new node.
Some additional verbosity in the Locator.
Development version bump.
Changelog format change.
Proper checks for connection success.
More verbosity for Actors.
Make it build on MacOS again.
Typo.
Ensure that Actors have no stall fds.
Comments!
Update README.md
Some minor wording.
Merge branch 'master' of github.com:cocaine/cocaine-core
