change label for 'disease or disorder'

[wdduncan]

An issue has been filed with OGMS to change the labels for disease and disorder.
Given the recent kerfuffle over the use of the labels 'disease', 'disorder', 'disease or disorder' in COB, I am in general in support of this (although it does have some downsides).

However, if OGMS changes its labels, then it would best if MONDO also changes to also change the label for disease or disorder to help mitigate future controversies.
