Added Reddit Section
Removed default header color, semanticness

Removed default header color (which shouldn’t have been there in the
first place), renamed classes so that it would be more semantic and
appliable to more elements.
better performance, intervals, started getReddit

Changed names of get functions to prevent confusion, increased
performance of getHackerNews(), added getEverything() function and set
it to repeat every 5 minutes,  added getReddit() for getting /r/webdev/.
