title: .meta file clutter in Unity (using SVN)
body: <p>Using SVN (Tortoise) in UNity3D clutters the script directory with .meta files. (one for every file)  It's gotten to the point that it really gets in my way as I go about my day.</p>
  
  <p>Question: Is it safe/is there some way to hide/mask them?  I'm worried that just setting hidden attribute might cause a problem down the line (if it's safe, I consider that a fine answer!)</p>
  
  <p>Note: Simply  sorting by type is not a solution here b/c of various cs and js file types mixed together in these directories) I'm joining a project already in development that was itself inherited from a different team, so yes, some oddities.</p>
