feature request: let mirror:order support directories and ignore list support

[Thomas Glanzmann]

Hello,
it would be nice if lftp would support ordering for directories, too:

        set mirror:order "*.sfv *.nfo Sample"

where Sample is a directory. And a exclude list would be helpful like:

        set mirror:exclude "*[COMPLETE]*"

to skip some directories/files when do 'mirroring'

Greetings,
        Thomas
