Setup current user info during init

[ryan]

Currently, the current user is setup when the wp() function is run from wp-blog-header.php. When WP is embedded, however, wp-blog-header.php is not loaded and the current user is never setup. Let's always make sure the current user is setup by calling WP::init at the end of wp-settings.php after plugins and everything else are initialized.

I like it. +1. Makes things more unified and simpler, which is always good :).

(In [6586]) Call WP::init() just before kicking the init action so that the current user is setup as early as possible. fixes #4181
