Work on the Market Interface (feel free to test it out so far, can't purchase items through the UI yet), More on UITable (needs work on headers still).

* Tables can now have headers (the layouts will require some more work before read to be used formally).
* Finished Market offers display, Item details display, and Item statistics display.
* Added getSelectedWidget to UIRadioGroup class.

Market TODO:
* Create buy/sell offer.
* Purchase sale offer or accept purchase offer.
* More item filtering features (weapons, types, depot only, vocation, etc).
* Item searching feature.
* View your offers (history/current).
* UI touch ups and optimizations.
