Beta Improved Navigation Map 0.3.1

Version 0.1.1 Changes:

Bug Fixes:
- Fixed roads being thick and inaccurate on smaller maps
- Map size limit should now scale with the actual size of the map (determined by the road nodes)
- Made the Improved Navigation System look more accurate to the Default Navigation System in the way roads are shown, before the map was kinda squished

New Features:
- Higher Zoom Limit, and more zoom levels
