Slick implementations of a festival page. CLEANUP!

Ok, so I've added slick.css before content.css so I can overwrite some default styling of slider. (see above)
I've removed Lobster and Oxygen fonts as they are not used in this page. Map is not used as well, so removing it allows ~2s faster page load time on slower networks. Don't load stuff which is not needed! 
Added OpenSans font which is one of the best ones for readability.
