Stability + Optimization Update (3.0.4)

# 3.0.4
## Backwards compatibility
- Old qualia: should be safe, but the file format has changed significantly. Back up any valuable qualia before playing. If you've modified your pocket qualia, you will need to enter it again for the new optimizations to apply
- Mods: Breaking changes! Firstly, the download location has changed from `lucid-blocks/lucid-blocks/lucid-blocks.exe` to just `lucid-blocks/lucid-blocks.exe`. You'll need to move your mods folder. Additionally, some significant changes to the core code have been made, so old mods may no longer work
## Content additions
- None
## Improvements
- Restoring a backup now creates a copy instead of overwriting the original qualia
- Huge save-file optimizations should drastically reduce saving + teleportation time while also reducing the odds of corruptions
- Backups are now created per save-file and recoverable in-game
- Optimized mimics, blasphemies, and alachs
- Added search bar to firmament embrace menu
- Reduced stutters when moving across chunk boundaries while many robust blocks are loaded
- Greatly optimized fruit seeds and style seeds
- Cached block icons to reduce boot time and likelihood of crashes on low-end devices
- More items now respect modified gravity (bombs, eggs/capsules, dropped items, hearts/balls/boulders)
- Minor optimization for dropped items
## Bug fixes
- Fixed bug where funnels at the origin would randomly accept dropped items globally
