Implement Web Share Target

[sorin-davidoi]

The Web Share Target API would allow native apps (e.g. on Android) to share text (and possibly other media) with Mastodon.

Use case:

• You find a nice quote you want to post on Mastodon
• You select it and click "Share"
• You select Mastodon from the share options (it will show up like a native app)
• Mastodon opens and the text is pasted into the compose field.

This is currently supported in Chrome Canary on Android (source) - but you can feature detect it such that it will automatically become available to everyone as soon as the feature lands in Chrome Stable (and other browsers).

I've implemented this at yuntan#3. I want to test it with Chrome canary on my Android phone but can't do because someone caches invalid manifest file. I can't estimate how long time to take to settle this incomprehensible behavior...

@yuntan Do you have any updates? Did they fix the issue?

@sorin-davidoi Sorry for inactive. I've been busy for job hunting and cannot respond to this issue until next week. Please refer https://groups.google.com/a/chromium.org/d/msg/blink-dev/_oUskZTzQxg/w4R_YnSXCQAJ about the incomprehensible behavior I experienced. Also note that I've not yet tested @rinsuki 's solution but may be good solution if you want to use /share endpoint instead of /web/statuses/new.
