QoL Improvements and More Character Designs

I've ported the improvements from Priestess Breeder back to Orgone Collector and made a few more improvements. This includes:

• About 1,400 available character designs for random encounters and custom NPCs vs about 400 before.
  • Note: Due to the large number of designs, I've automated the culling of inappropriate designs. A handful of designs present in the previous version may be missing now, potentially causing image loading issues for old saves and old custom characters.
• Playing without saving credentials locally works now.
• Better and clearer screen locking during api calls and image loading.
• Fixed the handling of mutually exclusive tags: a scene with two girls should show images with two girls now.
• Miscellaneous other bug fixes and QoL improvements
