v1.3.1 The Bones Update

Hello!

So this is just a minor update adding 6 variants of bone icons (mostly because I needed them for another map I'm working on). You can see most of the variants in the attached image, just enough to produce a "there were / are skeletons here" on the map.

The size of the bones are much longer when you compare to a 5-foot grid, but I sacrificed accuracy for clarity on this one (they were too hard to make out at smaller sizes for my liking).

Anyhow, hope you enjoy.
