Calendar view for signups

Just added three new signup sheet formats. You may now select one of:

• Month - Just Description
• Month - Just Name
• Month - Just Time

which shows the slots in a calendar-style month format. Hovering over a slot will bring up a summary of the slot information. The original list formats have been renamed to:

• List - Name, Time, and Description
• List - Just Name
• List - Name and Description
• List - Name and Time

to keep them all grouped together in the format menu.
