[Plugin: Mobile Client Detection Plugin] Fix for Add query_vars form not saving correctly

We discovered that the “Add query_vars” form field was saving/displaying the opposite of what it should. Here’s a fix:

Before (starting at line 327 in mobile_client_detection.php)

<h3>Add query_vars 'platform' & 'browser':</h3>
<select id="add_vars" name="add_vars">
    <option value="0"<?php echo(($mcd_options[3]==1)?' selected="selected"':'');?>>Yes</option>
    <option value="1"<?php echo(($mcd_options[3]==0)?' selected="selected"':'');?>>No</option>
</select>

Fix (starting at line 327 in mobile_client_detection.php)

<h3>Add query_vars 'platform' & 'browser':</h3>
<select id="add_vars" name="add_vars">
	<option value="0"<?php echo(($mcd_options[3]==0)?' selected="selected"':'');?>>No</option>
	<option value="1"<?php echo(($mcd_options[3]==1)?' selected="selected"':'');?>>Yes</option>
</select>
