The bulk update request #10051 is pending approval.

mass update walt_disney -> walt_disney_(character)
mass update walter_elias_"walt"_disney -> walt_disney_(artist)

Reason: I don't think we usually add middle names like that. His wikipedia page is just Walt Disney.

Also adding suffixes for clarity. A disambig seems overkill but I'm not sure which one should get the aliases. Can we just mass update without aliasing?
