fix the connected state icon
the icon that shows the state of the current connection current has some problems:
- it is tiny and hard to see
- it is always blue, which is confusing
- the connected icon looks like the disconnected icon
proposed changes:
- make it bigger
- make it different colors depending on the state
- make different icons (ask elijah)
there are really five potential states:
- starting up
- on
- turning off
- off
- error
