Release 1.1.7

* Guard against server not returning a Content-Type (test-suite server, apparently).
* Be more careful in using provided_context as serialized context.
* Move linkeddata and equivalent-xml dependencies to :debug environment in Gemfile; not needed for Travis-CI.
* Releases fixes for issues #14 and #15
