fixed old bug via regression test in page contract filtersThe binding variable for "min_length" and others was not passed correctly.We saw unexpected warning of the following form during regression test: Warning: Message contains a variable named 'min_length' which doesn't exist in the caller's environment:
Removed dependency on file-storage- there was a "silent" dependency of acs-templating to the file-storage, since it used many message keys from there.- The message keys went to acs-content-repository
Silence several log entries during initial install and during boot.The system should complain about missing caches just, when a) not during initial install, and b) if this is not during startup of an installed version
