Lexicons, woach to spoor, anilist to external

THESE LEXICONS ARE NOT FINAL, she screamed into the wind.

converts all references to woach.me to spoor.my to reflect the official
domain name.

Rename "feed" 3ld to "log" since the content here is separate from what
an activity feed would look like. Log has more in common with records.

I maintained the name activity over "spoor" here, because I want the
items to be easily digested by other services. I think "spoor" is
actually a more apt term than "activity" since "activity" is more
generic, than the specific mediaspoor it is, but it will do.

Changes the "anilist" entry to a more generic "external" entry, which
will be able to handle tvdb, or similar.
