Adds confirmation page to power off clients

This commit adds an extra view to ensure users do not power off clients
accidentally.

ogcp GET /poweroff returns the confirmation page and POST /poweroff
builds and sends the request to ogServer.

It also includes Spanish translation of the new strings.
