Fixes an issue which prevents changing module settings for eCommerce Storefront since the 'src' was zeroed out in _construct() (same for importexportController).  Basically meant you can't change action/view, module title, etc...  not sure if this has other ramifications since we don't use a src for most ecommerce stuff, but it is essential for an embedded module
Gets event registration back working, esp in regards to multiple registrants, however still needs some work
