Seaside-FileSystem package for Gemstone

> Hi Dale,
>
> We noticed that the WAExternalFileLibrary (Seaside-FileSystem) was not available in the Gemstone port of Seaside3.0
> Since this is a convenient package for us to do testing without Apache running on our machines, while still being able to use external files, we created a port for it.
>
> The current state is a bit hackery since it's not completely written in terms of Grease. It seems that Grease has a problem in Gemstone to read contents of a directory:
> The method WAExternalFilelibrary>>filesIn:do: is therefore written in terms of GSFile instead of using GRPlatform to do that.
>
> Although it's not necessary to have this in a GLASS setup, it's convenient to have this package in a setup without Apache.
>
> Current state of the implementation is attached.
>
> best regards
