Integrated upgrade.sh functionality, consolidated code to install dependencies, added ability to skip git operations, ensured the script can run from anywhere aimed at installation anywhere, ensured all git commnds worked from anywhere aimed at target folder, normalized specified install directory names (always get the absolute path).
This is a massive WIP and should not be trusted or used right now. However, major milestones have been crossed. Both message boxes and file dialogs are now properly subprocessed and work on macOS. I think by extension, it may work on runpod environments as well, but that remains to be tested.
