Update from 1.0.0 to 1.0.2

[sci2tech]

I did tell only use nightly if the only problem is from gui, not the config files.
@freinhard indeed that was the purpose. But ... squirrel mail security hole forced us to release based on v1.0.0 not on trunk, this way some problem were introduces. My advice was only for Cracknel who replaced reseller-functions.php instead just apply patch based on http://isp-control.net/ispcp/changeset/1924. Another way to fix this is to use version from v1.0.2 then modify according to r1924
