New REST call for set ACL right for multiple mediafiles at once

[forgacs]

A new REST call would be very handy to set ACL rights for multiple mediafiles at once.

REST call: mediafile/acl [POST]
with asset_id[]=....&asset_id[]=... etc.
Other parameters are the usual: aut_app[], aut_domain[], aut_group[], aut_group_id[], aut_realm[], aut_user[], aut_user_id[], replace.

This REST call sets the ACL rights to all of the mediafiles belonging to the given asset ids.

Example Request

mediafile/acl?asset_id[]=7pAkDsceysAZPo0q3PhjtBE1&asset_id[]=J2MKUJUcleMUfUcsZVDpdxi8
POST aut_user[]=user1

Example Response
