Add action hooks to wp-activate.php in WP network

[gdvwp]

Similar to the hooks in wp-signup.php:

do_action( 'before_signup_form' );
do_action( 'after_signup_form' );

these hooks should be added to wp-activate.php:

do_action( 'before_activate_form' )
do_action( 'after_activate_form' )

Purpose : allow signup and activate pages to be built/styled in a similar way.

20075.diff​ adds actions for before_activate_form and after_activate_form to wp-activate.php to help customize the activation experience. Moving to 3.7 for commit or discussion.

20075.2.diff​ adds docs to the two new actions.

It would be a good idea to pause while we determine the future of wp-signup.php and wp-activate.php through tickets such as #17948.

The actions in wp-signup.php have left us in somewhat of a strange place for a refactor. The same actions added to wp-activate.php could end up being strange as well. There are 3 different form possibilities depending on how/when the form is accessed, any actions should be better tailored to that. In the meantime, DOM could technically be modified through get_footer and get_header.

This could be closed as a maybelater.

Closing as maybelater. Complete lack of interest on the feature on the ticket over the last 2 years. Feel free to reopen when more interest re-emerges (particularly if there's a patch)
