Gang dashboard settings syncing in realtime, but…

there is an issue where when you uncheck a motor in a gang from a
second (or later) browser instance of the dashboard and then recheck it
in that browser instance, it doesn't appear to be checked again in the
first browser instance until you happen to hover over that checkbox in
that browser

Also removed some old image files from 'assets'
finished gang realtime synchronization

also, added a cute little background with a the background box mostly
opaque…but the dashboard might be loading more slowly

switched to using local variables in update func's

Now using local variables instead of global variables where possible in
the update function and the update functions for communicating with
keyspaces and synchronizing. Hopefully this'll improve performance
somewhat
