Title: Move System_SSH_Agent for psr-0

hi.

System_SSH_Agent does not conform to the psr-0. And so can not load by autoload.
underscore of class name should be directory separator.

```console
$ php composer.phar require "phpseclib/phpseclib:*"
$ vim sample.php
```

*sample.php*

```php
login('your', $agent))
{
exit('Login Failed');
}

echo $ssh->exec('uname -a');
```

```console
$ php sample.php
Fatal error: Class 'System_SSH_Agent' not found in ...
```
