Update BPEventHandler.java
Deleted old unused class.
Merge branch 'pulls/172'
Made it a config option, as this code will be redundant in 1.8.
Bugfix: A folder with the instance name minus two letters gets generated when a Circuit Database template is saved.
Fixed #165, Transposer sending ghost items with Factorization Sticky Barrel (untested, but most likely the cause).
Fixed #164, machines locking up and routing items to another place when too many stacks enter at once.
