Allocating Students in Contacts

When allocating unallocated students into timeslots on the schedules tab in Contacts, the popover will now automatically close when user clicks 'Copy'. 

​If there are no available timeslots (or if none have been set up), they will get a message telling them they need to set up timeslots before they can copy/paste into a timeslot. Field showing number of available timeslots is now visible at the bottom of the 'Schedule' tab.
