Add link to show batch page from table of not/completed batches

[shelleydoljack]

The pages show_batches_not_complete and show_batches_complete list the batches but there is no link to the show page for the batch. The show page provides more information about a batch and a way to delete a batch if a mistake was made. The show page appears after creating a batch but there is no way to get back to the page if a user navigates away from it. Add a link to the show page from the show batches complete/not complete pages. If the batch is complete, the erase button should be disabled.
