[Data] Improve data for Reddit and Feedly.
- Reddit stopped working for the Reddit comments page. Could not get it work, we possibly need to look into buildUnitAround code for that.
- Improved Reddit to work on different subreddits etc. Also, disabled Units by default on Reddit because it does not play well with RES.
- Added protected shortcuts for Feedly, and removed CUs data since they no longer seem applicable.
