alias waldo -> wally

BUR #12477 has been approved by @NWF_Renim.

rename wally -> wally_(where's_wally)
create alias waldo_(where's_waldo) -> wally_(where's_wally)

We have the copyright alias, so might as well have the character one.

Should the tag also be qualified as wally_(where's_wally)? Wally isn't the only character with that name; he's not even the most popular character with that name (wally_(pokemon)).
If we do we should also rename wally_(cosplay) -> wally_(where's_wally)_(cosplay).

It should be qualified. While both Waldo and Wally are actual names, Wally is a lot more common in usage than Waldo. While we have no other Waldo's, we do have several characters named Wally.

Makes sense. Edited BUR to add qualifier.
