new directory features

[Matthias Weiss]

Hi all,
        I've used code from Paul Davis libpbd and modified it to
suite my needs.
It's a directory scanner that returns a vector of strings that
are the names of the directory entries. One can use shell wild
cards and restrict the result to specified types (regular files,
directories, ... ) as well as further ristrictions ( size, owner,
... ).

I'd love to see the code merged into libcommonc++, maybe in the
Dir class. If you like the code please contact me, I have to
ask Paul to get his OK too.

The attached tarball includes a demo program - simply type make
to build it.

Some critics:
-the current class totaly lacks an error concept
-I doubt that it runs on a Windoze box, I've only tested it with linux.
-it offers no further functionality beyond that of the scanner
-for some reason the C-library doesn't recognise symbolic links
-I didn't spend time thinking about security as suggested in the
 security FAQ (at least I think I read something about it there)
