Updated Links page and Guestbook

Finally I found the time to updated my links page and guestbook. Both pages are now integrated into my weblog, so you can add an comment to the guestbook entry now for a general website comment or post your link into my link page.
I hope to make it now easier to leave a guestbook entry and insert links into my linklist. The biggest improvement IMO is that now the guestbook entries and link suggestions are also filtered with my MT-Blacklist. So spammers get blocked with one simple configuration.
