Changed login and logout buttons.
Now the buttons are directly visible instead of being hidden in a dropdown menu.
Code Cleanup and Bug Fix
Removed commented out code from index.html
Added a cancelAddCity that clears out the itinerary form when the cancel button is pressed.
Refactoring and Bug Fixes
Renamed cancelAddCity function to clearItineraryFields to make it a helper function that gets called whenever the itinerary files need to be cleared to prevent code duplication.
Fixed bug with previous check for repeated itinerary names. All add city functionality is now inside the callback function for the itinerary name check.
Fixed missing script files that broke test.html
Refactoring
Cleaned up datepicker code by removing unused functionality.
