 First of all I removed the
 {{{
 unset($wp_filter); // in wp-settings.php
 }}}
 and setup a static counter in '''add_filter()'''. On the first run, it
 will reset the $wp_filter to an empty array(). It will also make sure on
 each run the $wp_filter is an array().

 This allows plugins to hook even inside the wp-config.php if it includes
 the wp-includes/plugin.php file.

 I added 1-2 filters to all functions that list plugin files. This way
 plugins can alter these lists. Still got a lot to test but the filters in
 place do absolutely no damage, but provide me the testing ground for some
 deeper modifications.

 I also added 2 tweaks I carry on from version to version. A filter like
 this:

 {{{
 apply_filters( "query_template", $templates, $type );
 }}}

 located in the get_query_template() function allowing unitary management
 of template file array regardless of future WordPress changes.

 Also added an extra parameter to login_init action in wp-login.php.
 Special actions exist for each $action but needed the general one to tell
 me where it's calling from.

 {{{
 do_action( 'login_init', $action ); // This was missing
 }}}

 Changes are commented and my name attached to each change so you know who
 to blame or ask questions.

 Thanks.
