image URLs

I modified the slider-pack.js code to update hash for each image to allow deep linking.

Also got back button to work.

added a less variable which was causing a less compile error.

working example is here http://katewilhelm.ca/

hm, just found a bug in my code.. causing gallery to revert to first image. Need to fix that, and will update branch.

ok that should be fixed now.
