fix relayd startup/restart (ref #780)

Most of the time, there is no return value from the functions,
sometimes $retval is not evaluated, and sometimes it just seems
totally convoluted to do it when 99% of the configuration code
does not do it and works fine wihout it.

It's also not practical, because there is no no notion of a
rollback that would have to ensue in such cases.

fix filter reload with invalid relayd config, fixes #780

GUI sorting for now should be new, update, reinstall, remove.  Later
all those types ought to be merged into a single list with backwards-
compatible behaviour.  First of many neat firmware improvements on
our way to 16.7.  :)

(legacy) there are a few ACL's without a visible UI part included, which may result in less practical redirectings when the index is not authorized.

Add the license to the ACL, so we know for sure the menu is visible.
