New features

Users logged in outside their allowed area access (for example users staying after hours in an area when they only have business hours access) will now be shown in red in the status dashboard and other pages showing occupancy like the Jumbotron (thanks Princeton Micro/NanoFabrication Center for the contribution!).
Added customization setting in Customization -> Calendar to show configuration settings the user picked directly in the reservation feed, similar to the Configuration agenda feed (thanks UPenn Singh Center for the contribution!).
Added customization setting in Customization -> Status dashboard to hide projects the user is working on in the area occupancy tab (thanks Cornell NanoScale Facility for the contribution!).
Added new broadcast email option to send an email to all Principal investigators. It can be filtered to only be sent to PIs of active projects, and can also be filtered down to a subset of selected projects (thanks Cornell NanoScale Facility for the contribution!).
