Fix - Some 1.8 servers (maybe others as well) would not interpret the ignore list correctly and produce an NPE. This has been fixed.
Improvement - The ignore list is now converted a lot safer when grabbed from the config. The Material getter has been updated to one that is incase-sensitive and also support Material ID's, incorrectly spacing is handled, and the Material enum is caught properly if incorrect. An invalid configured enum/ID is skipped and printed to the console. The plugin will continue to work even if this happens.
