* Several constants are used to manage the loading, concatenating and compression of scripts and CSS:
* define('SCRIPT_DEBUG', true); loads the develppment (non-minified) versions of all scripts
* define('CONCATENATE_SCRIPTS', false); disables both compression and cancatenating,
* define('COMPRESS_SCRIPTS', false); disables compression of scripts,
* define('COMPRESS_CSS', false); disables compression of CSS,
* define('ENFORCE_GZIP', true); forces gzip for compression (default is deflate).
*
* The globals $concatenate_scripts, $compress_scripts and $compress_css can be set by plugins
* to temporarily override the above settings. Also a compression test is run once and the result is saved
* as option 'can_compress_scripts' (0/1). The test will run again if that option is deleted.
