Enable Drugs in Mook Sheet
This MR began with addressing #465 (closed). While I was in the code, I made other improvements:
- Always show the mook portrait
- Show "No weapon equipped" or "No armor equipped" when appropriate
- Stacking items works when dragging
- Fixed some UI alignment issues and cleaned up template code
Note: this is based on !653 (merged), so that must be merged first.
