More on Market (far from done), Minor Fixes, Edited Outfits Module, Some Cosmetics.

* Started building the market UI.
* More work on the market functionality.
* Fixes to the market protocol. (Known issue: if I use safeSend method from Market (like so: MarketProtocol.send~) is thinks it is a bot).
* Fixes to the market offer class.
* Outfit window will no longer display the mount box if you are using protocol < 870.
* Added getFeature to playermount module.
* Added isMarketable and getMarketData to the lua binding.
* Added lua casts for MarketData.
* Fixed typo in the module manager.
* Added new 'light flat panel' for more variation (can change later) will require some graphics for market.
* Added new functions to table lib.
* Fixed some styling issues from previous commits.
