Replace "collections/deque" with "queue"

The "collections" package has issues with array shims causing other
dependencies to break when least expected. This has been discussed
in multiple issues:

 - montagejs/collections#162
 - montagejs/collections#95
 - balderdashy/sails#2524

Another solution to this could be to depend on "collections@2.0.2"
instead which is a version without shims.
