FTP functions

[Xavier Delacour]

I've checked in an ftp package to octave forge. It implements

ascii, binary, ftp, mget, mput,
ftp_cd, ftp_remove, ftp_rename, ftp_put, ftp_get, ftp_mkdir,
ftp_rmdir, ftp_ls, ftp_dir.

They're bindings to ftplib-- a standard debian package, though small
enough to include directly into octave-forge if that is preferred.

The ftp_* prefix is necessary since Octave does not have overloading
based on first argument. One can also call these functions as
C++-style members, eg,
f=ftp("ftp.gnu.org");
f.cd("gnu/gcc");
d=f.ls();

Is MATLAB style OOP being done for 3.1, or do portions already exist?
(eg, could the SWIG runtime register class methods, even if all the
syntax is not ready?)
