Fix wrong Preview link on CMS pages grid

[Caprico85]

Description (*)

If you have a CMS page where the identifier has 4 or more levels (e.g. test/page/foo/bar), the preview link on the CMS page grid will not work.

The preview link only shows the first 3 levels, where the URL key has 4 levels.

The preview link is generated in Mage_Adminhtml_Block_Cms_Page_Grid_Renderer_Action. This class uses Mage::getModel('core/url')->getUrl(...) to generate the link. getUrl(...) calls Mage_Core_Model_Url::setReoutePath(), which tries to parse the URL with the usual module/controller/action structure and cuts off the fourth level.

Using getDirectUrl(...) instead of getUrl(...) fixes this as getDirectUrl(...) takes the URL as is, not cutting off the fourth level.

Manual testing scenarios (*)

1. Create a new CMS page. Set its identifier to test/page/foo/bar (or any other URL at least 4 levels deep).
2. Click the preview link on the CMS page grid.
3. You will get to the 404 page.
4. Check the URL of the link. It will be 'test/page/foo', not 'test/page/foo/bar' as specified in the identifier.

I confirm this bug with the latest OpenMage version + Magento Sample Data.

The About Us page has the URL key "about-magento-demo-store". Here are different scenarios increasing the path with one level

URL Key	Preview
about-magento-demo-store/1	OK
about-magento-demo-store/1/2	OK
about-magento-demo-store/1/2/3	Wrong

For the last scenario, instead of being displayed in the status bar as "about-magento-demo-store/1/2/3" it is displayed as "about-magento-demo-store/1/2", 3 is missing. By increasing the levels number, the URL will remain the same limited to two levels.

Tested and it works as expected. Screenshot attached bellow for a 10-level URL.
