Add a checkbox to allow administrators to re-send the welcome email to users.
Summary:
See title - This simply adds a checkbox to the "Edit User" page in the
admin view, to allow an administrator to re-send the "Welcome to Phabricator"
email.
Test Plan:
Sent myself another welcome email using the checkbox.
Created a new user using the admin panel, to make sure emails still get
sent for new users.
