LPFM and LMS map fixes in FCCdata.

Put in several modifications to the display and handling of LMS LPFM records that have extremely low powers and bring them back up to what they should be.  

Fixed a bug in the display of FM maps on LMS FM records where an amendment was filed.  

We note that there may still be some issues with LMS FM maps, especially for LPFM stations.  We will try to fix those on the weekend.
