Changes in foundation-orbit changes for switching to auto height orbit (without JS height calculation) with table layout

#### Changes in foundation-orbit for switching to auto height orbit (without JS height calculation) with table layout

All changes are in the orbit-table-layout branch. The change will make the LI's into a uniform height aligning to the parent UL. The UL will become a `display: table` and the LI will become `display: table-cell` making it always 100% of the parent. If the size of different carousel items is different, the LI's will always have the height of the biggest LI. The table-cell's also allow easy vertical align. Height management between orbit container and orbit is not needed anymore (no js for adjusting height) and the carousel will uniformly scale as needed.

* Removed on load  event (deprecated in jQuery 1.8)
* Removed any height manipulation on orbit UL
* Added Table layout style to UL and LI of orbit
