information on submit page should be editable in gui by admin

With the new create content menu which leads the user to drupaltest/node/add, it would be a good idea to make either (a) the text for each content type editable by admin or (b) give less detailed definitions for stories and blogs. The story definition assumes the site is using a submission queue, which might not be the case for many sites. The personal blog definition assumes that all sites will want readers to go with the personal diary definition of blogs.
