New feature: Highlight popular countries in country select

[ma4nn]

Description (*)

This PR backports a feature from Magento 2 (in a nicer way with option groups) that allows to configure countries that will be shown on top of the country list ("popular countries").

Also the code duplication for Mage_Checkout_Block_Onepage_Abstract::getCountryHtmlSelect() and Mage_Directory_Block_Data::getCountryHtmlSelect() is removed.

In addition a new event directory_get_top_countries is added, that allows to customize the logic (e.g. to determine top countries automatically from quotes/orders).

Manual testing scenarios (*)

Repeat the following tests 1.-5. for country dropdown in

• cart estimate shipping
• checkout billing
• checkout shipping
• customer account address edit
• customer account register

1. Disable config cache
2. Without any configuration the country dropdown looks the same as before
3. Configure one top country in System > Configuration > General > Countries Options > Top Countries and verify the country dropdown
4. Configure multiple top countries in System > Configuration > General > Countries Options > Top Countries and verify the country dropdown
5. Enable config cache, assure options are cached by reloading page multiple times and repeat steps 2-4
6. Verify product attribute country_of_manufacture uses non-sorted country list in backend
7. Verify product attribute country_of_manufacture can be displayed correctly on product detail page
8. In checkout select "Ship to different address", then in shipping form select "Use Billing Address" and change country value -> "Use Billing Address" should be unchecked then

Please re-check ... cache-key DIRECTORY_COUNTRY_SELECT_STORE_ is used at several places ... (not tested nothing, just an idea)

@SuSiSonnenschein111 thanks for your feedback (although it could have been a little bit more detailed).
By "several places" you mean Mage_Catalog_Model_Product_Attribute_Source_Countryofmanufacture?

But I agree, the result before sorting should be cached, I've pushed the change and extended the testing scenarios.

Moreover probably Mage_Catalog_Model_Product_Attribute_Source_Countryofmanufacture::getAllOptions() and Mage_Directory_Block_Data::getCountryHtmlSelect() should also be refactored further to remove the code duplication..
