Call init_progfile_dir() - on Windows, at least, it's necessary in order

to get the directory where the data files are stored, and on UN*X we
might have an option in the future to have it search there for data
files, to make it easier to run WireShark/TShark from the build
directory and have it find plugins, etc..
