Integrate Android "Share with topic" dialog

[binwiederhier]

emptymatrix suggested this on Reddit:

"to replace pushbullet in my phone, it requires to be able to share items from any android app to a ntfy topic. I mean: while browsing a URL in my favorite browser (Firefox, opensource, of course ;)) and I want to send it to a ntfy topic, I just would need to click on Share button, select ntfy, then ntfy would show a list of target topics, so I could pick one.

"target topics" would be a list of topics (editable in the ntfy UI in the app) to which I'm not subscribed but I would like to share often. Each topic would represent a device."

This actually sounds like fun to work on, so I'll do this next.

That's the way to do it, Phil. Forget test driven development - fun driven development rules! :-P (SCNR)

That's the beauty of your own project; I can do whatever I want. 🥳 😎

This is done and will be released with the next app release; see binwiederhier/ntfy-android#16
