Added the posibility to pass the timeout to FTP.connect, not only when

instantiating the class. Docs and tests are updated.

 Connect to the given host and port.  The default port number is \code{21}, as
 specified by the FTP protocol specification.  It is rarely needed to
 specify a different port number.  This function should be called only
 once for each instance; it should not be called at all if a host was
 given when the instance was created.  All other methods can only be
 used after a connection has been made.

+The optional \var{timeout} parameter specifies a timeout in seconds for
+the connection attempt. If is not specified, or passed as None, the 
+object timeout is used (the timeout that you passed when instantiating the
+class); if the object timeout is also None, the global default timeout 
+setting will be used.
