- flatten nested "lindex" structures- use numeric comparison operator for truth value comparisons- use "lassign" instead of multiple "lindex" operations
- avoid setting one-use variables for frequently called code- fold multiple upvars to a single one- make indentation more regular- fix one case of double dollar
fixes for download-zip:- require login for zip-downloads (keep away spiders)- return "not found" on if ids are no acs-objects- clean temp-files on errors
