Here is update and improvement of this answer. It works with django 1.6 and redirects to where you came from.

class ActionInChangeFormMixin(object):
    def response_action(self, request, queryset):
        """
        Prefer http referer for redirect
        """
        response = super(ActionInChangeFormMixin, self).response_action(request,
                queryset)
        if isinstance(response, HttpResponseRedirect):
            response['Location'] = request.META.get('HTTP_REFERER', response.url)
        return response  

    def change_view(self, request, object_id, extra_context=None):
        actions = self.get_actions(request)
        if actions:
            action_form = self.action_form(auto_id=None)
            action_form.fields['action'].choices = self.get_action_choices(request)
        else: 
            action_form = None
        extra_context=extra_context or {}
        extra_context['action_form'] = action_form
        return super(ActionInChangeFormMixin, self).change_view(request, object_id, extra_context=extra_context)

class MyModelAdmin(ActionInChangeFormMixin, ModelAdmin):
    ......

Template:

{% extends "admin/change_form.html" %}
{% load i18n admin_static admin_list admin_urls %}

{% block extrastyle %}
  {{ block.super }}
  
{% endblock %}

{% block object-tools %}
    {{ block.super }}
    

    
{% csrf_token %}
        {% admin_actions %}
        
    
    
{% endblock %}
