use CGI->param instead of CGI->Vars , CGI->Vars has caveats , its broken by design

Also, get rid of sub uploader, its pointless :) as long as $query exists, so do the temporary files, its pointless to copy them

Also don't interleave sub declarations and main program logic flow, and make more subs, write like 

use ...
Main( @ARGV );
exit( 0 );
sub Main {
   my $query ...
   my @attachements = snafu_attaches( $query );
   my $mime ...
}
