Filtering Hoppers 1.0.7

Hey everyone! Another update, fresh from the oven!

+ Fixed filters sometimes not properly saving due to using a poor way to get the hopper you're viewing
+ Fixed the entire chunk hopper feature, which was broken from head to toe
+ Fixed duplication glitch (no further details to avoid it from being exploited in older versions of the plugin)
+ Fixed hopper getting fully stuck if the first item in the chest it's taking from isn't in the filter

Enjoy!
