Inflector bug fix in singular()

[eluser]Unknown[/eluser]
Currently, singular() results in the following:

horses -> hors
bases -> bas

I recommend the following code change in the singular() function:

Code:

$last3 = substr($str, -3);
$last4 = substr($str, -4);

if ($last3 == 'ies')
{
...
}
elseif ($last4 == 'sses')
{
...
}

Those few line changes fix the singular() function.
