Fix various admin/monitored state output printing

  log messages for admin_state make a little more sense now
  html/csv/json output over http cleaned up so they all have the
same consistent columns of data with the same meanings (just
current state and real state, which are often the same).  Forced
states are indicated by an "!" suffix on the current state, and
a change of color in the html case.
