Fix up all the easy virtual ... SK_OVERRIDE cases.

This fixes every case where virtual and SK_OVERRIDE were on the same line,
which should be the bulk of cases.  We'll have to manually clean up the rest
over time unless I level up in regexes.

for f in (find . -type f); perl -p -i -e 's/virtual (.*)SK_OVERRIDE/\1SK_OVERRIDE/g' $f; end
