Messed up my credits here

Fix for issue #5: Changed credits to include the proper author of
pthreads, @krakjoe
Added an empty output file for PHP errors.

Simply as that, added the log folder and decided to place a clean file
into it. I didnt put the Logs folder into /System, because this is more
relevant to the whole app. However, I will use that folder to log a lot
of things - like installations, patches and updates. So I might even
need a script to clean this folder if it gets too messy at times x)
Added proper app-icon

If you are porting drag0n, the icon can be found in:
drag0n.app/Contents/Interface/icons/green.png
plist was buggy, changed that. Its unbuggy.

Changed version and copyright information, thus made the new icon
"really" work =)
