/**
* Misc stuff and REQUIRED by ALL the scripts.
* MUST be included by every script
*
* Among other things, it contains the advanced authentication work.
*
* Order of sections for common.inc.php:
*
* the authentication libraries must be before the connection to db
*
* ... so the required order is:
*
* LABEL_variables_init
* - initialize some variables always needed
* LABEL_parsing_config_file
* - parsing of the configuration file
* LABEL_loading_language_file
* - loading language file
* LABEL_setup_servers
* - check and setup configured servers
* LABEL_theme_setup
* - setting up themes
*
* - load of MySQL extension (if necessary)
* - loading of an authentication library
* - db connection
* - authentication work
