I updated the files for the build process to fit the current wireshark
version.
I don't know much about it so a just copied the missing parts from
another module.
I'm not sure of it's right, so please have a look at it.
Modifications:
* added plugin.rc.in
* added moduleinfo.nmake
* updated Makefile.am/nmake/common
* removed unused variable from opcua_application_layer.c
* fixed unused parameter warning in opcua.c
I tested it on Windows with VC6 and on Gentoo linux with gcc 3.4.6.
