Fixed Custom currency format validation fails if the format starts with {value}

Hello,

There is a problem with saving custom currency format in Admin -> Appearance -> Languages -> Edit Language page. If the custom format value is set to {value} $ (or any other currency sign) the form fails with error:

Currency format must contain at least "{value}"

Suggested fix:

In file /src/XF/Admin/Controller/Language.php, on line 113 it says:

if (!strpos($input['currency_format'], '{value}'))
{
    $form->logError(\XF::phrase('currency_format_must_contain_at_least_value'), 'currency_format');
}

which should be replaced with

if (strpos($input['currency_format'], '{value}') === false)
{
    $form->logError(\XF::phrase('currency_format_must_contain_at_least_value'), 'currency_format');
}

Thank you!
