Wider track line to make more visible
Renamed "drawMETARText" to reflect that it's for drawing TFR text
Moved the logic to check for the pref being enabled in drawObstacles and drawRunways to main loop to save some processing overhead
Created a new function drawRunwaysNew that has a shadow behind numbers and also rotates the numbers so they're upright in track-up mode
Testing displaying a toast when the center button is pressed to display user location in ATC terms (eg "8 miles Northwest of KRIC", 3,500').  Not working yet
Expanded comments and some cleanup
