Include tower call name in airport data

I believe the tower call name is missing from our data. For example, KBFL shows 
as "Meadows Field" on the tapcard, but when communicating with the tower on the 
radio, you should call "Bakersfield Tower".  Here's the Airport Communications 
section for the airport from this page (NFDC login may be required to view the

UNICOM:  122.95 MHz  
ATIS:    118.6 MHz   661-399-9425 24 Hours
RADAR SERVICE:   Approach / Departure    
BAKERSFIELD APPROACH:   118.8 MHz   APCH/P BASIC RADAR IC    (SOUTH)
    118.9 MHz   APCH/P BASIC RADAR IC    (NORTH)
BAKERSFIELD APPROACH/DEPARTURE: 270.3 MHz   APCH/P DEP/P BASIC RADAR IC  (NORTH)
    284.625 MHz APCH/P DEP/P BASIC RADAR IC  SOUTH
BAKERSFIELD DEPARTURE:  126.45 MHz  DEP/P BASIC RADAR IC     (NORTH/SOUTH)
BAKERSFIELD EMERGENCY:  121.5 MHz   EMERG     
    243 MHz EMERG     
BAKERSFIELD GROUND: 121.7 MHz   GND/P     
BAKERSFIELD TOWER:  118.1 MHz   LCL/P     
    257.8 MHz   LCL/P     

Do we already have the "BAKERSFIELD" call name in our database? If not, we 
should get it and also turn the name into mixed case so it displays well.
