TODO list:
- fix [flash], add width/height parameters?
- check that PHP syntax highlightning works well
- add other languages?
- add validation regexp to [email], [flash]
- add validation regexp to [quote] with username
- add ACL check for [img]/[flash]/others (what to do when an unauthorised tag is found? do nothing/return an error message?)
