More fixes & Compendium Browser

A big update today:

• Corrects the Signature Heavy Pilot Weapon tags (now only "loading")
• Fixes a bug in which pilots exported at LL0 would fail on import
• Fixes a bug in which a pilot imported from the clipboard would not correctly mark configurations as their own
• Fixes a filtering error preventing some mech systems from showing up
• NEW FEATURE: the GYGES Core Bonus Threat increase now shows up on equipped weapons
• NEW FEATURE: Compendium
  • Browse Licenses, Manufacturers, Frames, Weapons, Systems, and Pilot Gear
  • This will probably expose some bad or missing LANCER data, so stay tuned for updates and corrections
