v10 Added TravelerGroupDialogFragment

New DialogFragment that will display a list of the Travelers available
for this TripComponent.
v11 TravelerGroupDialog
fixed student bug

- see line 77. fixed some of the weird Activity related code to be more
consistent, but line 77 had your actual error. wasn't the activity. the
second argument should be a string or the ID of a string. temp[i] is an
int, thought it was the ID of a string resource and thats why it would
crash
