Script Summary: Looks for all mailto:sage hyperlinks and changes them from the default blue colour to red. This is useful as you can distinguish posts with sage in the email field from posts with genuine email addresses.
UPDATE: Now works with the new http://boards.4chan.org URLs.
UPDATE: Now works with the 4chan extension thread expander.
UPDATE: Minor fix to the sage finder. "sage" does not have to be at the beginning of the email.
UPDATE: some boards (/f/lash in particular) don't recognize noko in the email field, so they create a blue hyperlink for it.
See http://userscripts.org/scripts/show/46568.
UPDATE: works with the revamped 4chan HTML.
