Please consider adding Pushbullet support back

[Techman]

I was wondering for a while how come Pushbullet notifications stopped working when I finally discovered that support for it was removed. Pushover requires a license purchase on every platform one would want to use it on last time I checked, which is greater long-term compared to Pushbullet's subscription service, but it doesn't change that Pushbullet is still free for the purposes of using it for notifications.

I have kept my Pushbullet configuration options in weechat since those weren't automatically removed in hopes that one day it can be reconsidered.
