Subject: [PATCH] v1.4

- EventLoop will now pick an image within 2 mins of live footage
  and copy it to the root directory of the buff dir. This can be
  used by user interfaces as a live stream thumbnail.
- Gray option is no longer enabled by default.
- The default compare command will now use the Gray image format
  internally instead of relying on the external Gray option.
