create implication wiping_sweat -> sweat

similar to wiping tears

There's quite a few posts under wiping sweat that have no visible sweat: post #4403704, post #2813082, post #3850953, post #3745235, post #3525048, post #3298899. Arguably they should be tagged with something like wiping forehead etc, but it's hard to debate that those characters are not wiping away sweat.
