CORE: Batch Download using Aspera

As part of the June 27th Core release, users now have the ability to batch download assets into a single Aspera Connect request. Previously when a user attempted to use the Download All via Aspera feature, each request was sent individually which would  limit the users bandwidth per transfer. The batch Aspera download feature is a single request and can dedicate all the bandwidth to a single transfer which allows users to get their files faster.
