Apparently I missed releasing 1.4, so this is the changes for both versions

1.5 (05/25/2013):

- adds plugin settings for custom jquery selectors

- fixes for side-by-side columns, internally scrolling elements 

- adds support for lazy-load of ajax loaded content

1.4 (03/14/2013):

- updates lazyload script to 1.8.4

- prevents lazyload from occurring on iOS (scrolling issue in iOS6)
