Replace Pushover module with Notify

[jacroe]

Replace the current Pushover module with a Notify module. This will be where we send out notifications by email. Pushover, or through the web interface (TBD how later). Something like:

function alice_notify(string $title, string $message, array $services)
#Services:
function alice_pushover(string $title, string $message)
function alice_notificationEmail(string $subject, string $body)
function alice_notificationWeb(string $subject, string $message)

Then using those listed in $services, make calls to each function.

(Hopefully what I'm trying to say will make sense later when I actually implement this.)

No reason to have one function that simply calls other functions. It will be probably just as well that we call them individually. Won't implement.
