V0.4 - 2015-06-16 - owagner

  - Settings: MQTT broker address is now a text field and thus allows entering of hostnames
  - will now check whether the title information changes during progress
    checking, and will republish the "title" topic if a change was detected
  - increase progress publish rate to 20s (from 30s)
  - avoid "kodi2mqtt" as a name in the documentation and addon itself, and instead stick to "MQTT Adapter"
