Zach Brown 7b0c576798 Restructure PaperSpigot as a new set of modules
Allows us much greater control over the Spigot portion of the code
and makes us more "proper"
Credit to @Dmck2b for originally passing the idea along a while back

Subject: [PATCH] Use Offline Player Data Once if Required.
If we are online mode and the only copy of player data we can find is the player's offline mode data, we will attempt a once off conversion by reading this data and then renaming the file so it won't be used again.
