Statuses compatibility with mastodon API

[zeerooth]

Extension of #3

We're missing most of the components of the status API, mainly:

• Translate a status #309
• See who boosted a status (See who boosted/favourited a post in mastodon API #367)
• See who favourited a status (See who boosted/favourited a post in mastodon API #367)
• Boost a status (Update, boost and unboost a status using mastodon api #306)
• Undo boost of a status (Update, boost and unboost a status using mastodon api #306)
• Bookmark a status
• Undo bookmark of a status
• Mute a conversation (requires Notifications #149)
• Unmute a conversation (requires Notifications #149)
• Pin status to profile
• Unpin status from profile
• Edit a status (Update, boost and unboost a status using mastodon api #306)
• View edit history of a status (requires Save post edit history #330)
• View status source #310

@aumetra could you please assign this one to me? I'll get started on the key endpoints here

[aumetra]

I'm going to (very sneakily) steal myself the issues for status translation and for "View status source", if that's okay with you

I'd very much welcome that, go ahead :)
