Aliasing ear_bite -> ear_biting.

Reason:

Ear_bite has 39 images tagged with it. Wouldn't it just be easier to just correct those 39 images?

ear_biting has 42 images, ear_bite has 45.

Even though it would be easy to just edit the tags, it's probably worth aliasing it here because both are almost equally used tags, and people will continue tagging ear_bite without realising they should actually be tagging it ear_biting.
