Not all problems - in some cases, "argv[0]" isn't an absolute pathname.

On Win32, you can get the absolute pathname of the currently running
program by calling "GetModuleFileName()" with a null pointer as the
first argument; I've checked in a change to use that, in Win32, to guess
what the installation directory is.  (It's only a guess; it also
searches "C:\Program Files\Ethereal\plugins\{version}", if it finds it,
so that if you've installed plugins there, and are running Ethereal from
a source directory in which you've built it, it'll find the plugins
there.)
