Highlighting updates on "Phone/SIM Details" page

Created by: E3V3A

The current Main page Phone/SIM Details doesn't show network updates very clearly. The way it currently looks is this:

What I would like to see is that items that have just changed are highlighted in (for example) yellow and then slowly fading away into the normal blue text with time. Perhaps around ~20 seconds or so.

This would probably require that the code is using a ACTION_PHONE_STATE_CHANGED listener, and not a polling mechanism, if not already implemented. It has to use a listener and not a polling mechanism or otherwise we risk missing quick changes. In addition, any changes will have to be immediately added to the EventLog of the DB. See #215 (closed).
