Fixed barcode(?), Made years DDL + Dynamic, Cleaned Code

Fixed Barcodes.
Reason it was appearing weird before: the display barcode upon entering
info appended with barcode size info, the unload localStorage display
barcode didn’t. Now BOTH functions do not  input any sizes.

Select Grad_Year is now a drop down list /select (it appears as a roll
menu on IOS now). To make it dynamic, function
populateYears(startingYear) was created.

Cleaned up code and added Anthony’s script at the bottom of the page
from html into index.js as populateFaculties().
