v1.4 change to Mage_Adminhtml_Block_Catalog_Product_Edit_Tab_Super_Config_Grid

[benz]

OrganicInternet_SimpleConfigurableProducts_Adminhtml_Block_Catalog_Product_Edit_Tab_Super_Config_Grid copies the _prepareCollection() method of the Mage block in the title.

However in version 1.4.0.1 the mage block has changed slightly to include a check for ReadOnly in the grid:
if ($this->isReadonly()) {
$collection->addFieldToFilter('entity_id', array('in' => $this->_getSelectedProducts()));
}

Well spotted, cheers.
(I've added it but I'm still testing so not uploaded anything yet.)
