title: "Show All Files" option missing in VS Database Project
body: <p>The VS Database Project does not seem to have the "Show All Files" option in the Solution Explorer.  Does anyone know of a way to turn the option on in VS?</p>
  
  <p>The "Show All Files" option on the solution explorer actually does two things.  With the option selected, VS shows "hidden/nested" files within the project AND it shows files within the directory of the project that are not currently part of the project.  (It shows the latter with a ghosted icon.)</p>
  
  <p>While DB projects may not have nested or hidden files within the project, there is no other way that I know of  to have the solution explorer show files within the directory that are not part of the project.</p>
  
  <p>Also, while this action occurs within the solution explorer, it is actually a project issue.</p>
