Wireshark dissector

Starting point for a wireshark dissector realized with LUA.
DLL as a standalone LUA "modul" only for blowfish decryption, can be linked with lua52.dll from wireshark, nothing else needed (using the lua headers from Intwars, using the recommended MinGW toolchain).
Work in progress, but everything needed should now be possible in LUA.
