remove implication pov_eye_contact -> pov
remove implication pov_eye_contact -> looking_at_viewer
create alias pov_eye_contact -> looking_at_viewer
Aside from being a pov looking_at_viewer combo tag, there are too many people treating it as just looking_at_viewer and ignoring the pov stipulation, wiki be damned. Might as well alias it to looking_at_viewer so pov doesn't need a cleanup every week.
