The PNG spec allows for only one method of compression inside of IDAT chunks: inflate/deflate (Zlib). However, Zlib lets us do some crazy things as long as we make it happy by giving it an Adler hash and spawning some other needed data thus emulating a part of the Zlib spec :-) I just hope this works as I think it does :P

Compress:
- The "crc bug" is not a bug, it is actually a feature (the function returns an Adler hash, not a crc hash. This is more usefull for PNG files..) and was "fixed" by using the proper function instead of munging a substring
- Zip files that are BZip2'd are now supported for extraction :-)
CAPTCHA:
- PNG generation now returns positive numbers for CRC, length, height and width!
- We generate a variable number of images

- changed docs/AUTHORS to reflect the recent code re-use in functions_messenger.php
- pleasing the users a little bit more by using table constants. :D
- login box if "mode" is not allowed -> posting (thought about trigger_error integration, but we do not need this that often).
