Correct Setting Page h4 Content

Notice both h4 tags in the setting page display “Success Alert”. Whereas the second one should likely say “Error Alert” (or something to that effect).

 <h4>Success Alert</h4>
      <p>Timer (default is 3000) <input type="text" name="swal_cf7_duration_success" value="<?php echo get_option('swal_cf7_duration_success'); ?>"/> ms</p>
	  <p>Title (default none) : <input type="text" name="swal_cf7_title_success" value="<?php echo get_option('swal_cf7_title_success'); ?>"/></p>
	  <hr />

	  <p>Title (default none) : <input type="text" name="swal_cf7_title_error" value="<?php echo get_option('swal_cf7_title_error'); ?>"/></p>
