Have fields update as exchange rates do

Currently the exchange rates plugin shows the converted
rate at the time of last user input.  If the fx rate
changes the send and receive tabs do not update.

This makes them update.  It also means that when enabling
the plugin, if the user had input a BTC amount in the send
or receive, the other fields will refresh.  This didn't
used to happen - they stayed blank.
