Fixing comments

I have received a whole bunch of complains that comments are not working properly. There were few problems:

• Registered users could not post comments, because they were redirected back to blog’s main page.
• Replies to comments didn’t work for the same reason as above.
• Replies to comments couldn’t be added in some browsers.

After a few dirty hacks and brilliant fixes by yours truly, I think these probems should be mostly over. If you still cannot comment or reply to comments, let me know via email or, well, comments. :)

P.S.: Stupid ‘Preview comment’ thing is gone. It was causing too much troubles.
