Include items and cancel options from jQuery ui sortable

[MaazAli]

Having the item and cancel options would really help when we don't want all the items in the list to be sortable. If there is a way of doing that currently, that would be great?

{{#collection content=people moved="movePerson" item=".allowed-sortable" cancel=".sortable-disabled"}}
