Merge branch 'feature/fs_silence_detect' into develop
[BUGFIX] Support stop-beep and mix attributes on Rayo record model
[BUGFIX] Support input match content-type
[CS] Allow CI to fail on ruby-head

Travis is bust
[BUGFIX] Input match documents should be in CDATA
[BUGFIX] Don't absolutely require CDATA tags for match documents
[CS] Allow activesupport 3.x or 4.x
[BUGFIX] ActiveSupport::Inflector is needed
[BUGFIX] Nokogiri::XML::Element was being provided by niceogiri
[CS] Output should use a URIList object rather than an array directly

This allows for future things like conversion to/from SSML
[BUGFIX] Use RS grammars to avoid weird spec bug
[CS] Run test suite against active support 3.x if on Ruby 1.9.2
[BUGFIX] We were still relying a little on niceogiri monkeypatches
[BUGFIX] More reliably import attribute values
