Subject: Several changes have been made in this commit, which together with
 the previous commits result in version 1.1: + The rules for the Apache and
 nginx configuration have been changed and redirects now all requests to the
 index.php. + A router class has been added which now handles all requests
 that arrives at the application on the index.php. + Short-hand functions
 "PAGE", "POST" and "USER" for use in templates added to get specific item
 data by ID. + More language variables have been added to the core language.
