Override hashCode method in AbstractRegion

Browse Source 
This commit fixes the PlotSquared issue where running a PlotSquared command could result in intense lag on the main thread. This was mainly seen with running the /p info command on an extremely large plot.

Since #world can be null, the uniqueness of this hashCode is not the best, but since it's essentially just a collection of BlockVector3's, I don't believe this change will break anything. If it does, please let me know! Feedback on the uniqueness of this is welcomed.
