Update ct-jquery-matchHeights.js

- added animation between height changes, for (external) breakpoint-based resizing
- settings now set outside of the loop
- tested in OS X 10.9.2 Chrome 34, OS X 10.9.2 Firefox 29.0, Windows 7 SP1 IE11, iPad iOS 7.1.1 
- iPad iOS 7.1.1 didn't always resize the height when the device was rotated
