Greasy Fork

- Add support for x.com
- leverage a twitter bug that sometimes show tweets from users who blocked you to show those tweets in more situations.
- a bit of experimental code, disabled by default.

Bumped middleman version to get a fix for a bug that prevented uploading media in your tweets/posts/replies.

Catching up with Twitter's monetization efforts: disable any config that's about subscriptions, upsell, or super follows.
This should make the app clean again.

- straightened out of the code, making things hopefully easier to understand.

The upsell items had a tendency to come back after a while. Turns out the Twitter app occasionally asks the server for a user's config flags again.
This change intercepts those flags and re-asserts the configuration we want.
