Minor error

[ekandreas]

First! Thank you for a great plugin and I have been looking for this for a long time and considered to write my own. The code looks clean and verified.

Att row 558 in /blocks/block.widget.php a check for empty array is missing.
Warning: Invalid argument supplied for foreach() in /Users/andreas/Sites/layout/wp-content/plugins/layout-engine/blocks/block.widget.php on line 558

foreach($in_widgets as $w)
{
$available_widgets[] = $w;
}

should instead read:

if (sizeof($in_widgets)>0){
foreach($in_widgets as $w)
{
$available_widgets[] = $w;
}
}

Thanks!
