gc and encrypted metafiles

The patch was designed to allow both, but I didn't want to mess up
gc() so I didn't add an option for local metafiles.

Essentially the two lines in Brackup::Target that read:

     my $decrypted_backup = new Brackup::DecryptedFile($tempfile);
     my $parser = Brackup::Metafile->open($decrypted_backup->name);

would need to be rewritten:

   my $parser;
   if($use_local_metafile)
   {
     # Assumes local metafiles are unencrypted.
     $parser = Brackup::Metafile->open($local_metafile_name);
   }
   else
   {
     $self->get_backup($backup->filename, $tempfile);
     $decrypted_backup = new Brackup::DecryptedFile($tempfile);
     $parser = Brackup::Metafile->open($decrypted_backup->name);
   }

But the outside loop in gc() needs to be rewritten, in order to
account for local metafiles and provide $use_local_metafile flag and
the $local_metafile_name above.

I just tested and it seems to apply cleanly to 1.07.
