remove the "item cannot be both damageable and stackable" from logs

[Soppki]

whenever i look at the logs all i see is the error "item cannot be both damageable and stackable" and its getting really annoying my suggestion is to disable stacking for damageable items so when you enter the command '/allstackable set all (previous size) (new size)' it ignores damageable items instead of trying and coming up as an error. ty :P
