#20 bbcodes don't work

[milahu]

the bbcodes ([b][/b], [i][/i], ...) don't work
properly. i've fixed the problem. bold, italic and
underline already work. i'm also going to add different
colors you can choose for the text. i've also planned a
little menu where u can easily insert emoticons or
bbcode via javascript. i'll upload a bugfix/extension soon.
