Async library is not added to package.

[parhelium]

Async lib is only included in tests ( Package.onUse ):
package.js line 44
api.addFiles('test/lib/async.js', client);

but should be also included in package ( Package.onUse ), because it is used in
lib/permissions-common.coffee in line 94

    async.each users, ((user, callback) ->
      Meteor.users.update {_id: user}, update, callback), callback
