Updated arcade-organizer script

[MisterAddons]

I'm looking for testers before I submit a pull request. I've added a massive amount of options to the ini file for fine-tuned filtering of arcade cores. This goes in concert with the updated MRAs, and has helped me identify some typos and inconsistencies.

Instructions:
Copy _arcade-organizer.sh and _arcade_organizer.ini to /media/fat/Scripts
Run _arcade-organizer.sh
Delete /media/fat/Scripts/.cache/arcade-organizer/last_run between each successful run if you want to do full builds

Please submit issues through Github:

Thanks!
