Encode url's for social media links
Removed old app-controls reference
Added map.js back in.
Fixed grayscale in Firefox because it wasn't working.  Also, svg filter gray was too light and didn't match the standard filter gray.  Removed some browser based filters that aren't actually implemented.  Note, transitions don't work on the svg based filter, so there is no filer transition on hover in Firefox.  There is no gray filter support in desktop opera at this time.  Mobile Opera 15+ uses the webkit engine so grayscale filter should work there.
