 Every type of page in the admin area has an equivalent
 ```load-[whatever]``` type action, which is triggered before any HTML has
 been rendered. This is handy if a plugin needs to process some data which
 might require a redirect header to be set, or to affect HTML which is
 rendered before the admin screen main content (e.g. admin notices).

 The exception to the rule is the importers. I propose adding an action
 which would allow plugins and themes to execute code at this point as
 easily as they can in other areas of WP admin.
