Saera v2.2 is released to OpenRepos!

Changes:

• Saera cleans up after her own alarms
• Config file added (in /home/nemo/.config/saera/setting.json)
• Support for Internet sources for voice recognition added - currently only Wit.ai has been implemented. This is DISABLED BY DEFAULT to preserve user privacy; to enable it, set internet_voice to true in the config. It will only use internet voice if wifi is connected, as it uses a lot of data.
• Saera will now mute the audio of any currently-playing music while listening, to improve recognition accuracy.
• Help has been added - ask Saera "Help" or "What can I say" and she will give you a list of suggestions.
• Fixed navigation
• Fixed handling of contractions ("What's", "who's" etc.)
