web: multi-select

Modified the display so that if it's a template we display it
correctly opposite the text, and provide classes that can be used
in the display to differentiate between the main label and the
descriptive label.

Added a sort key, so the select can sort the right-hand pane correctly.

Fixed the `this.selected` setters to use Arrays instead of maps.
Theoretically, this is terribly inefficient, as it makes it
theoretically O(n^2) rather than O(1), but in practice even if both
lists were 10,000 elements long a modern desktop could perform the
entire scan in 150ms or so.
