For 1.3.11 I think of adding a global config to enable it on all 
external links. This is done easily.
I'll just finish with debugging php5 and do the final tests then.

config-dist.ini:
; If GOOGLE_LINKS_NOFOLLOW is true, ref=nofollow is added to
; all external links to discourage spam. You might want to turn it off,
; if you want to improve pageranks on external links.
;GOOGLE_LINKS_NOFOLLOW = false

config-default.ini:
GOOGLE_LINKS_NOFOLLOW = true
