style changes, fixing margins for higher resolutions, updating svg image...

@swbloom @mmeiers @stulees @donnapep some further style changes to for higher resolutions. Added a map marker to show where the user is but still to figure out how to reset the map completely to remove the directions. Noticed that my laptop was struggling with the background animation at the higher resolutions even with the translate 3d included so will look into that.

Updated and cleaned up the SVGs and added in the watermarks. I think that the scan animation effect may be out of line on some sizes so please let me know what you see. 

Thanks!
