Add missing Status methods, except for Status editing

[bocops]

• adds: translating, bookmarking, muting, pinning
• postStatus now has language parameter
• deleteStatus now returns a Status for subsequent editing
• reblogStatus now has visibility parameter
• implements posting of poll statuses
• implements status scheduling
• removes getCard (removed in Mastodon 3.0.0 after deprecation in 2.6.0)
• adds entities Poll, ScheduledStatus, Translation
• makes all new methods available via Rx
• includes tests and test assets for all new methods
• does not implement status editing (see Implement post editing functionality #124)

Closes #125.

Hello @bocops ! First off, thank you very much for this great contribution! 😀 This is really awesome. I made some comments (just minor things). I'd say, let's merge this to master very soon and then start writing some integration tests for this.

@andregasser I hope I got all documentation links and annotations this time around. Thanks for checking! :)
