views_board 1.0.0-beta1

First release.

• A Board format for Views: any view of entities stored in SQL shows as cards in columns, one per value of a field, optionally split into lanes by a second field.
• Cards move by drag and drop or from a keyboard Move menu, with undo. Each move checks update access and field edit access, validates, and saves the entity normally.
• A kept order with a weight field, work-in-progress limits, totals, due dates, Add links in each cell, and full screen.
• Events to veto or react to a move, add lanes and change the Add links. The README lists the stable API under "API and stability".
• The Views Board Tools submodule exposes reading a board and moving a card as Tool API tools.
