jebsmag DISABLED - > FROZEN
after discussion with L.Favacque, N.Carmignani and L.R.Carver the disabled concept is not clear in the jebsmag application. better to have a new state called "Frozen"
this state should be visible only above certain allarms not all.
for exmple if the allarm is temperature too high, the state of the maget displaied should be allarm and not frozen. if the allarm is current close to maximum, then the state should be Frozen (dark green for example)
