Handle alerts for possible closures

[brianzelip]

All Ys are closed today for some event, yet the schedule that this app scrapes doesn't reflect this. As a result the output from this app shows that there are three lap swim times today.

Check for alerts when scraping data and include any in the logged output.

Alerts are represented in a XHR response:

Request as URL
