Rationale: The `IMHEX_PLUGINS_IN_SHARE` is a hack to prevent the appimage from loading plugin from system imhex installation, like /usr/lib/imhex/
In reality, I do not think people compile plugins specifically for the AppImage (plugins must be compiled for the specific imhex & compiler version the imhex binary is used), and this lets us remove the hack
* build: Tried to streamline and fix AppImage building
* build: Tried fixing build
* build: Added back version key
* build: Fixed AppImage name
* build: Fixed python bundling, fixed ELF uploading
* build: Don't upload a bunch of AppImage garbage files in the portable ELF version
* build: Fixed another wrong library path
* build: Removed old manual AppImage building scripts
* Simplify creating an AppImage
- package.sh packages the build result into an AppImage. It requires
squashfs-tools to work
- runtime-x86_64 is a binary distributed by the AppImage project that takes
care of extracting and running the image
* use AppRun from AppImage project
* clean up no longer needed bits
* Keep docker way of working around
- Docker now also uses `package.sh`, so no more need for FUSE.
- Fetch binaries instead of storing in git.
* Fix details
* wait a little longer for the container to start
