Memory leak for massive databases #93

Hey. There is a problem with the plugin loading every block into the blocksInChunk hashmap in the class me.prunt.restrictedcreative.storage.handlers.BlockHandler on startup.

My database is 1GB in size with 15 million blocks stored in it. Everytime my server runs, it goes up to max memory ridiculously fast. I ran a heap dump and took a look and here are the necessary images:

Is it possible the plugin is loading all the blocks in the DB into the map on plugin load instead of loading the blocks on chunk load and removing them on chunk unload? Would make the hashmap much less massive for larger servers
