Maxime Quandalle 2c0030da62 Implement multi-selection
The UI and the internal APIs are still rough around the edges but the
feature is basically working. You can now select multiple cards and
move them together or (un|)assign them a label.

// A inlined form is used to provide a quick edition of single field for a given
// document. Clicking on a edit button should display the form to edit the field
// value. The form can then be submited, or just closed.
//
// When the form is closed we save non-submitted values in memory to avoid any
// data loss.
//
// Usage:
//
// +inlineForm
// // the content when the form is open
// else
// // the content when the form is close (optional)
// We can only have one inlined form element opened at a time
// XXX Could we avoid using a global here ? This is used in Mousetrap
// keyboard.js
