updated perl binding for IDA Pro

I add functions for accessing cmd structure
Now you can do things like this:

#!perl -w
use strict;
use warnings;
use IDA;

my $addr = ScreenEA();
my $href = ua_ana($addr);
my $str = GetDisasm($addr);
if ( defined($href) )
{
  my $iter;
  printf("real: %s, %s:\n", $str, get_mnem);
  foreach $iter ( keys %$href )
  {
    printf("%s: %X\n", $iter, $href->{$iter});
  }
  my $op_idx;
  for ( $op_idx = 0; $op_idx < 6; $op_idx++ )
  {
    my $op = get_op($op_idx);
    last if ( !defined $op );
    printf("operand %d:\n", $op_idx);
    foreach $iter ( keys %$op )
    {
      printf(" %s ", $iter);
      print $op->{$iter} . "\n";
    }
  }
}
