Admin Actions: Action form doesn't takes care whose submit button was pushed.

[Martin Mahner]

If you have a action-bar on top and on bottom, the response_action function always reads the action from the bottom action-bar.

(In [10408]) Made a bunch of improvements to admin actions. Be warned: this includes one minor but BACKWARDS-INCOMPATIBLE change.

These changes are:

• BACKWARDS-INCOMPATIBLE CHANGE: action functions and action methods now share the same signature: (modeladmin, request, queryset). Actions defined as methods stay the same, but if you've defined an action as a standalone function you'll now need to add that first modeladmin argument.
• The delete selected action is now a standalone function registered site-wide; this makes disabling it easy.
• Fixed #10596: there are now official, documented AdminSite APIs for dealing with actions, including a method to disable global actions. You can still re-enable globally-disabled actions on a case-by-case basis.
• Fixed #10595: you can now disable actions for a particular ModelAdmin by setting actions to None.
• Fixed #10734: actions are now sorted (by name).
• Fixed #10618: the action is now taken from the form whose "submit" button you clicked, not arbitrarily the last form on the page.
• All of the above is documented and tested.
