Version 2.2.0 Update

- Fixed event handler conflicts with devices that are both click and touch enabled. e.g., Windows 8.
- Made all slider variables public, stored in `slider.vars`. This allows manipulation of `slider.vars.minItems` and `slider.vars.maxItems` on the fly to create different fluid grids at certain breakpoints. [Check out this example demonstrating a basic technique](http://flexslider.woothemes.com/dynamic-carousel-min-max.html)
- Fixed calculations that were causing strange issues with paging and certain FlexSliders to move out of alignment.

A new demo file was added, dynamic-carousel-min-max.html, and should be moved to the flexslider.woothemes.com site when approved (the link above will remain broken until it is added).
