Clint's Version of thumb scroll bar
Completed all features except the scroll bar switching - 2 bugs remaining

only working on the first page loaded due to a class being used as the
selector that the data-attribute is being stored in. Talk to Ryan.
- Selector for the thumb image switcher function is bad. talk to
Michael.
