Main site's plugins not loaded on wp-activate.php in multisite mode

[rahal.aboulfeth]

In wordpress 3.3.2 ( also 3.4 and trunk ) when the site is installed as network mode, none of the main blog plugins are loaded on the user activation page.

This is important in case we use some plugin functions in the header or the footer ( like qtranslate for example ) , as well a various plugin widgets.

More importantly, plugins hooks can't work as plugins is not loaded.

There may be something I'm not grasping in the current behavior, but I made a patch to fix this.
