Added notifications for visiting chefs

You can now get notified when visiting chefs are on campus! A menu is available from the toolbar on the main screen that allows you to enable notifications and configure what visiting chefs you want to be notified for. You can also toggle if you want to be notified 1, 2, or 3 hours before the chef arrives on campus.
Other changes in this commit:
- Updated maps URL to be compatible with the new RIT map (however they don't open correctly- this is outside of my control)
- Removed button linking to OnDemand at the request of RIT ITS
