Added a secondary endpoint that uses a different source for parsing earthquake information. hraun.vedur.is (original endpoint) was lacking some of quakes that was on vedur.is main site.
handle errors when source is returning something unusual and making our parsing method fail.
Return error response if requests library return res as null.
Merge branch 'earthquake-sec' of git://github.com/haukurk/apis into haukurk-earthquake-sec
Fixed the /sec endpoint and did some cleanup
