Tag alias: bared_teeth -> clenched_teeth

create alias bared_teeth -> clenched_teeth

Unless someone can see a meaningful distinction there.

Using post #1267788 as an example, not all bared teeth are clenched.

Point taken. In that case, a wiki definition for bared_teeth would be useful. How about "Teeth bared in a threatening display. May or may not be clenched."?
