Enable / Disable Multiple Products

This extension adds multi-product "Enable" and "Disable" functionality to Product List on Admin Dashboard.
Two new buttons, "Enable" and "Disable", are added next to the default "Insert", "Copy", and "Delete". It works differently than other similar extensions, which only allow a change of the product status by clicking a single product at a time. This extension makes use of the checkboxes to select multiple products (or all) and executes upon clicking the appropriate new button. A success message is displayed upon completion indicating the number of products enabled/disabled or an error message if no checkboxes are chekced. The system cache is updated so that changes take effect instantly on the website front-end.
