Invalid UTF-8 excerpt was sent in trackback

[Hideki ONO]

Version: serendipity-1.1alpha5(s9y_200605241538.tar.gz)

Invalid UTF-8 excerpt can be sent in trackback because UTF-8 encoded excerpt string is cut with bad boudary in multibyte characters.
Attached patch uses serendipity_mb('substr') instead of substr().
