Add wake word functionality to stream

[jahrichie]

• a stream should allow a wake word property, like "hey google", or "hey alexa" functionality.
• a wake word should be max 140 characters
• wake words should be a configurable option string
• wake word should take a callback function it will execute in bash when a wake word is heard, and pass the spoken words after as an argument
• options for how long after a wake word is said the process listens for after would be a nice to have
