Patch 5.0.4

[theorzr]

• API: Fixed lwjgl fix for LWJGL version 3.4 and onward, which were not supported because of a bad implementation
• API: Support for guessing java-runtime-epsilon (this was not needed for Mojang versions anyway)
• CLI: Added suggestion for installing Debian/Arch system-wide JVM packages when no compatible JVM is found
• CLI: Removed deprecated help message for old syntax, and various help improvements
• CLI: Fixed implementation of search limit, which was not respected when filtering
• CLI: Add debug line to show the process ID
• Doc: Added partial usage example in README (related to Invalid Session - Help? #275)
• Internal: Updated pyO3 version so that we no longer get errors while developing (note that Python binding is not yet ready)
