The King Features definition doesn't work as it stands, so I've
broken out all of the comics I use into separate definitions and
fixed them.  I used the non-kingfeatures comic sites where possible,
as King Features serves comics with an awful mess of referer-checking
iframe'd Javascript designed, I suspect, to prevent automated scripts
like this one from accessing it.

Comics affected by this commit:
Baby Blues
Beetle Bailey
Bizarro
Blondie
Hagar the Horrible
Hi and Lois
Marvin
Zits
