Feature #8007 (New): Request for registration form hook

• view_my_account hook - for account page
• view_users_form hook - for user edit page
• view_account_left_bottom hook - for user profile page

But it misses a hook for registration form!

That is if I need to add some new fields (let's skip why I can't use custom fields) I won't be able to add them to registration form (custom fields are supported for it). That's I believe another hook should be added to registration form.

P.S. I attached patch for adding such hook.
