corrected shebang in scripts
InitializeIptables modified for multiple bugs and new features

- we can now set proxy ports in the orWall settings, meaning we needed
  to pick them in preferences in order to apply rules

- there was a nasty bug with the init-script, most probably due to
  crypted data directory; this prevented the userinit.sh script to be
  launched at boot time, meaning there were some network traffic before
  anyone could do anything.
  The init-script is now installed in /system/etc/init.d directory.
