Updating UGWA to a new school year

Update firstDay and lastDay in js/utils.js to the first/last day of the school year. (This is for alternate schedule fetching.)
Set ALT_KEY in js/utils.js to a new localStorage key name to store alternate schedules in. It can follow this format: [gunn-web-app] alts.20xx-xx.

You should set LAST_YEARS_ALT_KEY in js/utils.js to last year's ALT_KEY so that it clears the stored alternate schedules.
NOTE: You might not want to do this until after the school has released alternate schedules on their Google Calendar, so it only force updates when it's ready.

Update datePickerRange in js/schedule.js to have the first and last days of the school year. Note that months are zero-indexed here, so August would be m:7. (This is for... the date picker range.)
Update an if/else statement in the ugwaifyAlternates function in js/schedule.js to use the new school year's two years.

For example, for the 2054-55 school year, it'd look like

if (month > 6) date = new Date(2054, month - 1, day)
else date = new Date(2055, month - 1, day)

This is for determining which year a month-date pair is in. UGWA stores alternate schedules weirdly.

Updating Ugwita

Ugwita has been marked as deprecated. However, if you still want to update it,

Change firstDay and lastDay in lite/data.js. This is the same as step 1 in the previous section (because UGWA copied from Ugwita).
You'll also need to update startDate and endDate in lite/main.js; this is kind of like in step 3 where months are 0 indexed.
