Text Adventure

Added the ability to roll on gear (needs testing.) 

Changed default settings to promote higher frame rates 

Fixed bug where you couldn't buy from a vendor if the item was on the second page, even when using the correct index given from /ta vendor. 

Added a better range indicator system. 
Added a method to mark dangerous drops. Dfdanger is based on the angle you're facing so it will warn if the location is to your left or right. Dfdanger has the ability to export coordinates and import coordinates to map areas that are hard to travel like Thunderbluff or Teldrassil.

improved the way that marked cells were drawn on the map by reducing space between horizontal o's to not cause them to attempt to draw on the next line.
