Implement the i3bar JSON protocol (with fallback to plain text)

Browse Source 
If the first line of the input starts with {"version":, then the input is
considered to be JSON, otherwise it is interpreted as plain text.

Only the "full_text" and "color" parts of a block are currently understood by
i3bar.
