some minor fixes

/br sspl - says to click same spot again to apply, clicked same spot and nothing happens
/br layer - gives an error message "there was an error handling a FAWE command: [See console]
/br clipboard - doesn't let me execute because of max radius of 5, however am unable to set a lower radius as there is no option for it
/br butcher - tried to kill some mobs, but didn't work (nothing happened)
/br splatter - tried to execute the command, nothing happened
