Title: adding "Emergency reroute" option to email-ext-plugin

Our Jenkins cluster requires some maintenance work during which we
prefer all Jenkins emails (failures, success, unstable, etc) to be
rerouted to an email address (or addresses).

I've added this option in my forked git repo of email-ext-plugin.
There's now an extra "Emergency reroute" in the plugin configuration
page. If it's not empty, then that will be the recipient list of the
current email excluding all other potential recipients.
