Widget "Captive Portal Status" small bug

[Gertjan]

The widget "Captive Portal Status" contains a smal visual bug.

To see the effect:
You should have more then one portal user connected.
Like this:

more users connected will be fine also.

Now, disconnect a user with the "grey cross button" at the left side.

When this button is clicked, someting like this is sent:

href="?order=&showact=0&act=del&zone=cpzone1&id=2d84ec64268bc40d

&showact will be set … to 0 (zéro).

Now, have a look at line 75:

$showact = isset($_GET['showact']) ? 1 : 0;

$showwact will be set to "1" because 'showact' 'isset' (and has a value of 0 (zéro))  ;D

Result: have a look at your screen: the widget breaks visually because two more columns are shown.

I have tested and propose this for line:

$showact = (isset($_GET['showact']) && ($_GET['showact'] == 1)) ? 1 : 0;

Noticed the widget breaking a couple of days ago. Gonna try out your solution.
