Several changes have been made in this commit, which together with the previous commits result in version 2.0 (database update required):v2.0

+ Implemented [core]: A new database field has been added to all tables to define optional "arguments" for a page, post or user through the content editor. These arguments will be parsed into key->value pairs and can be used within templates to do something special. Please read the wiki of this repository for further information about this new feature.
+ Bugfix [core]: The function "makeSlugURL" had not convert uppercase umlauts to lowercase because "strtolower" was used instead of the multibyte equivalent "mb_strtolower".
+ Optimization [core]: The first regular expression within the function "makeSlugURL" has been optimized (checking for uppercase characters at this point is unnecessary because $string is only lowercase).
+ Optimization [all templates]: Markup for the pagination.php has been simplified (a little bit).
+ Optimization [admin template]: The javascript for the arrow key navigation has been outsourced to the main.js file.
+ Optimization [admin template]: The javascript file will now be included with the "defer" attribute.
+ Optimization [standard template]: Some language variables have been changed.

Database update to version 2.0 (no existing data will be lost or changed):

ALTER TABLE `page` ADD `argv` VARCHAR(100) NULL DEFAULT NULL AFTER `body`;
ALTER TABLE `post` ADD `argv` VARCHAR(100) NULL DEFAULT NULL AFTER `body`;
ALTER TABLE `user` ADD `argv` VARCHAR(100) NULL DEFAULT NULL AFTER `body`;
