- don't produce hard errors, when folder_id is not a valid number. The validator of the page_contract is called before the type of the query variables are checked. The db-query in the validator raised the hard sql error rather the intended error message
Remove broken check for empty folder name.A previous change in this line prevented one from instantiating applicationsvia this UI. However, the check for an empty value is obsolete anyhow...
- undo previous secure-cookie change since it interacts badly in situations where "RestrictLoginToSSLP" is "1" and https is available: In such cases, e.g. the login page is redirected from a http (insecure) url to an https (secure) page. But when later continuing on the http connection, the user appears to be not logged in, since a well-behaved browser does not send the "secure" login coockie over the insecure connection.
