Update to allow running outside of an IDE

- Updated the LWJGL installer (microsoft were stupid and it ended up
installing HTML files instead of DLLs)
- LWJGL installer now downloads the actual LWJGL zip and extracts the
natives on-the-fly
- Halved the despawn count-down on entities
- Animations can now load inside a jar file.
- Fixed NPEs when logging downloaded files
- Created circle mapper.
