Update: gear returns, Scrap for parts, fullscreen fix

Fixes from your bug reports, all sent through the in-game Report a bug button. Thank you.

- Gear you lend out comes back. When a hero borrowed a guild weapon or armor, their own piece could end up sitting in the guild armory instead of returning to them. Fixed on every path.
- New: Scrap for parts. The Armory said "sell or scrap" but had no scrap. Now guild gear you are not using can be scrapped: half of what it was made of comes back as crafting materials (scaled by how worn it is), and the armory slot is freed. Nothing comes back below 25% durability, but the slot still clears. No trader needed.
- Fullscreen quest screen with a big party. With six or more heroes in fullscreen, the actions panel at the quest location could get squeezed to a sliver. It now keeps its size and the panel scrolls instead.
- Crash reports now include the build and the screen the game was on, so the next one tells us where it happened.

Thanks to everyone using Report a bug. We read every one.
