Improved Path Tool Thumbnails

I always thought the preview thumbnails for the different paths you can build in the game were ugly. On top of that they weren't a very accurate representation of what you actually build in the game.

Then came the new paths of the Return to Jurassic Park DLC. The thumbnail images had a different lighting to them and the images made it look like the paths were somewhere between the width of the narrow and wide paths of the JW era. Also the corners of these images were sharp instead of rounded. Not much of this is noticed that much until you start playing with a mixed era mod.

This mod replaces the images with better looking ones that are more representative of what you actually build in the game (now also includes the banner poles in the middle of the wide paths!) and makes all the images uniform in their look. The RTJP paths are 70% the width of the narrow paths of the JW era. This is now correctly represented.

* Requires the Return to Jurassic Park DLC (I think? Perhaps someone could test it without the DLC and see if it works too?)
