Minimaps need love too. Addresses LEGACY-181

Changes
 - Removed Zoom Level 3 (was never properly implemented)
 - Removed rotation on compass directions and the round map
 - Added arrow to roundmap
 - Added checks to make sure offset for entity faces on the minimap are
   correct based on the minimap type (round or square)
 - Reset X and Y position of minimap when the Square checkbox is toggled

Known Issues
 - When the background option is disabled, the square map texture and
   compass directions are not aligned properly
 - Red square appears near bottom left side of the arrow on the square map
 - Entity faces poke outside the map at times, not as severely as before
   but still noticeable
