Doesn't work if the View has a pager

If the view this is used on has a pager, and has its data over multiple pages, then this can't be used to email all users in the list.

This is a crucial feature for lists of users that are too long to show on one page, but where nonetheless an admin user may want to email all of them -- for example, a list of OG group members, or Commerce customers.

Given that VBO has a UI for selecting all the items even in a paged view, perhaps the dependency on this module should be re-added?
