Bugfixing update

Commit has been tested on the bus
Changes:
-Changed listener update interval from 500->1000->1200
-Once bus approaches stop, app will display the next stop (Assume
correct order)
-Input screen fixed (derped on last derp commit)
-No longer says bus stop twice, will need to test more

Bugs:
-Says nearby stops sometimes if radius is too close to another stop (J -
Anderson @ Alvarado and Alvarado @ Anderson)
-Correlation between bus speed and error distance for bus to announce
stop (~200 feet so far, 1000 ms), should not occur
-On some occasions lowering request update time will result in bus stops
being announced more than once.
-(Minor) Volume level too low to hear stop
