[ftputil] Implementing PEP 343: The 'with' statement

[Roger Demetrescu]

Hi,

I have a suggestion: FTPHost could implement __enter__ and __exit__
methods necessary to allow the use of `with` statement like that:


with ftputil.FTPHost('host', 'username', 'password') as host:
    host.chdir('/some/path')
    # do some more operations


Cheers,

Roger
