Question Desk 2.24.0

Added

• Email QA Facilitators, for a whole event (a button on each event in Admin). Each QA
  Facilitator, including the event's own, gets one email with the room screen and queue
  links for each of their sessions in the event, with scheduled times. Ended sessions are
  left out. Asks before sending.

Changed

• Calmer question rows in the queue. Answer now is the one solid button; Phones,
  Answered and Dismiss are quiet, and line up from row to row.
• With Group automatically off, the queue doesn't talk about grouping: ungrouped
  questions are simply "Questions", with no word-based sub-groups or "not grouped yet" notes.
  With it on, word-based sub-groups appear only while grouping is actually failing, and a
  slow run is mentioned once for the block instead of under every question.
