[Ovmsdev] Push notifications by email

Happy new year everyone :-) I just added an email notification channel to the server code, following a request for a personal OVMS server. https://github.com/openvehicles/Open-Vehicle-Monitoring-System/commit/172a50... As the Android notifications need the hard coded C2DM channel and C2DM is no longer supported, this is primarily meant as an alternative for those using their own server and not wanting to build their own App. It might also be useful for other users & the main server -- I would like being able to receive my Twizy trip reports by mail.
