I've updated the FeedPoint app with the a few requested features:

- The feed list screen now has the "mark as read" button. You don't need to expand the menu for this.

- It now allows sorting the feeds by time they were created, such as "sort by newest" and "sort by oldest". This sort is set on the feed level and persisted across the execution of the application.

- You can change the theme from inside of the app itself to be either "light" or "dark".
