Import products update

This is an update for http://marius-strajeru.blogspot.com/2009/11/import-simple-products-for-barrmy.html

Starting version 1.4 you can only perform product updates 'programmatic' only if Magento thinks you are in the admin panel.

If you try to do this from a non-admin page make sure you put this

Mage::app()->setCurrentStore(Mage::getModel('core/store')->load(Mage_Core_Model_App::ADMIN_STORE_ID));

before you call

$product->save();
