add motice for PHP installations without cURL module

PHP installations without the cURL module (usually contained in packages
like php5-curl or similar) no longer get a fatal error on pages that use
the forum feed applet. Instead they get the error message that the app-
let will show when the XML file could not be retrieved. Additionally,
the admin CP page for forum feed configuration will now show a warning,
if the cURL module is missing.
