autocomplete complete on uuid field for create

So 3 things to notice: 1.the uuidArray needs to be in the form of
label/value (NO IDEA WHY), but it can't just be a regular string array
if we want the array to be dynamic (i guess?)
2. $("input#uuid").autocomplete('option', 'source', uuidArray); is
called whenever the uuidArray changes, which basically says to update
the autocomplete values (obviously)
3. The reason cookies wasn't working before is that it has to be in the
form of key=value syntax. The reason it was getting overwritten is that
it replaces any cookie with same key name. Also, If you set a new
cookie, older cookies are not overwritten.
