Rename select_action to select_item which makes more sense. Rename the checkbox itself select_item_id to allow other types of selectes in the future. Move the code to determing selected items into ItemTable since this is where the form is generated, and we know how it was build.

Refactor the 'select all checkboxes' javascript into a separate file so it can be used on other tables easily. Add a test for the select all checkboxes javascript. Remove the label from the 'delete' column (which is now a 'select all' column as we may have other actions) and move it to the first column as per balsamic mockups.

Refactor the code to handle file input type (use a custom button, and automatically submit upon file selection) so that it can be used on multiple pages. Add an upload button on the view/edit page.
