VID-176 vet spacing

VID-176 The original goal was to lessen the amount of vertical space in the second (details) screen of the VET.  While I was in there I cleaned up VET.scss a bit, removing unused selectors and swapping id selectors for class selectors.  I also organized it by screen (All, 1st, 2nd and 3rd).  

Also created window.VET so global functions could be namespaced there.
