Fixes #875

Port 4c03e05a4e to glitch-soc

This introduces new requirements in the API:

  `/api/v1/timelines/tag/:tag` now accepts new params: `any`, `all` and `none`
  It now returns status matching tag :tag or any of the :any, provided that
  they also include all tags in `all` and none of `none`.

Fixes #855

The `hasMore` property of timelines in redux store was set whenever an API
request returned only one page of results, *even* if the query only requested
newer statuses (using `since_id`), causing `hasMore` to be incorrectly set to
false whenever fetching new toots in a timeline, which happens each time
an account's timeline or media gallery is visited.
