Add config page for all RSS feeds

[shawnphoffman]

Overview

I tend to lose track of what RSS feeds I have open so I decided to add a config screen for them. Basically, it just lists all of the open RSS feeds with some basic metadata and a button to close them. A modal lists the episodes associated with the feed and copy-to-clipboard option.

Open Questions

• Localization. Is there a process for this? Do we leave the keys out of the JSON files or include them with English strings?

Thanks, this is a good idea. For localization just updating the en-us.json file is perfect. At some point a more scalable localization solution will be put in place but for now I just run a script that adds the English strings to all the other json files.
