Added new art for the Tricky Pick, thanks viceanddecay!

- Updated Modular trait description to match implementation
- Enforcing having a free hand to switch Tricky Pick damage type

Fixed rune item bonus to attack rolls disappearing after switching damage types. I'm starting to see a pattern...

Fixed effects other than damage from property runes not carrying over when switching damage types.

Fixed a bug where changing damage types would disable extra damage from property runes and other effects

Added Modular weapon functionality
