 0.07: Added @jeffmer's awesome track viewer
 0.08: Don't overwrite existing settings on app update
       Clean up recorded tracks on app removal
+0.09: Change default GPS period to 10 (1 is overkill for most uses and makes things slow)
+      Added RAM keyword to functions & other tweaks to speed up rendering
+      Going 'back' from track view now doesn't load again
