Buddy rework, adjustments, and fixes

I cleaned up the code a bit (I'll clean it up more as I make more progress) and fixed a bug with buddy slots. Now buddies aren't overwritten!
A few reworks and adjustments

I reworked the buddyIDs array to store only player UIDs instead of IDs. I also reworked buddy deleting so that it deletes buddies from the array.
Code cleanup

Cleaned up some of the code. I mainly just removed useless helper methods.
