Crash Utilities

- fixed crash when relogging

- fixed typo that caused thousands of packets instead of 1 or 2 (oops)

- added Output to callItemClear Command, it now says how many items in world and what the current limit is set to

- added some additional shortcuts to entities and tileentities commands (due to a bug in Mojang code these shortcuts do not provide suggestions for further options)
