Update configuration to restore compatibility with backend

The Apache site configuration file has been rewritten since ARSnova
Mobile and Backend are now running in separated contexts. The Apache
rewrite rules are obsolete and have been removed. Only a redirection
for the configuration is needed for ARSnova to work correctly.

The Puppet file for Socket.IO configuration has been replaced by a
configuration for entire arsnova.properties.
