New integrations

The comsat-shiro module contributed by @roded (thanks!) through #53 allows custom implementations of Shiro Realms to perform fiber-blocking calls when invoked by fibers (see the docs for details).

Improvements

• Many dependencies have been upgraded both in the Java and Clojure modules.
• Other minor improvements, some from the community (like @andreiursan's 57cff66, thanks!)

Closed issues

• #44
• #50
• #54
• comsat-actors-undertow and comsat-actors-netty support for concurrent requests within the same session has been made safer and more configurable.
