Sleazy Fork

• Support new frontpage feed dropdown used for selecting timeline.
• Made cards faded out if the update was more than 24 hours after their creation.
• Changed faded opacity to 50% rather than 40%.
• Changed follows to only refresh once per hour, because it takes a few seconds and can be annoying.

Thanks to a helpful user on the Chub Discord, I found out that the API key is available in localStorage, saving the user from having to manually input it.

• Switch to more robust check for cached values existing.
• If we fail to modify one card, don't skip all cards after that.
• Check token validity by checking if the account endpoint gives us the example data, and if so, alert the user about it.

Cache non-placeholder API keys so that even if the API_KEY variable gets overwritten during an update, we can load the actual key from storage. Update readme with setup guide.

Actually hide the card if it is marked as hidden, sigh.

Fixed the hide button not doing anything.
