Minor Revision for Thrown Weapons Handbook

We have published a minor revision of the Thrown Weapons handbook. The new handbook can be found at: https://drive.google.com/file/d/1CscBWZLAGdvF7blXqXTn18hR3yavvbiC/view?usp=sharing

The main change was a few adjustments to the plumbata rules as a result of the plumbata class this past weekend.

The minimum spear distance was also corrected to 20′ from 15′. 

I also added a line about all marshals being required to have a waiver on file with the Clerk of the Roster. That has been policy for awhile, but was not included in the handbook.
