A few tweaks

A few tweaks

 * Deal with send errors by actually exiting, which should cause pod
    restart to reconnect (or backoff, or whatever)
 * A bit more logging when you can't cast a map on DIY action decodes
 * Wait to refresh off states on lights, preventing IMMEDIATE turn-off
    when you first start the program, or have the pod moved elsewhere.
    Normal off->on and all other actions are unaffected.
