update_karoshi_upload2.cgi - bug fix for double scrollbar.
Samba3 support removed in the web management.

Prior to this the latest version of the web management could be installed on a server still running samba3.
Since we are no longer doing any testing on samba3 this has now been removed and the samba4 scripts have now been moved back to the normal folders.
home_folders - modified to set ownership of folders just to make sure.

This has been put back due to a problem rsyncing between servers where the folder ownerships were not set correctly.
