bookable_resources 1.0.0-alpha4

Fourth alpha. Still not for production sites: the data model and the forms may change before beta.

Run database updates after upgrading: equipment gets a weight field (update 10001).

Calendar

• A Legend link at the end of the calendar's filter bar explains what each mark means, in two groups (a booking's states and the calendar's), with samples drawn with the calendar's own classes, then how to make a booking, with a small moving picture of a drag. Submodules add their marks through the new hook_bookable_resources_calendar_legend(), and an entry that needs a permission is shown only to whoever has it.
• A selection over more than one day, in any view, or in the week view's All day row, opens the form with one All day row per day.
• Closed hours and holidays no longer count as bookings when a selection or a move is checked. An empty day no longer turns into a maintenance block, and a booking that runs past closing time can be moved again.
• All-day bookings say All day on their card instead of "0:00".

Booking dialog

• The dialog no longer closes on a click outside it. The forms have a Cancel button; the ×, Cancel and Esc close it.
• Whichever way the dialog closes, the calendar clears the selection that opened it. A new bookable:dialogclose JavaScript event says it closed.

Reservations

• The reservation summary shows the group, the site's own fields (in the booking form's order, only when filled) and the equipment asked for, through a new facts prop any module can append to.
• The management editor keeps what only staff decides in the Administration box, in order: status, the notice, both comments and the maintenance block.
• Equipment has a weight: the listing is draggable, and the booking forms, the summary and the resource's selector follow its order.

Settings

• Where the section opens: the list of groups or the unified calendar. The breadcrumb's root, the way back and the list's own address follow it.
• Show a link back to the calendars, on by default, for sites whose breadcrumb already offers the way back.
