title: Clear/Remove all connections in a Xcode project
body: <p>I'm a newbie to Xcode, Objective-C and iOS programming (fully comfortable in R however, so familiar with programming concepts).  I'm working my way through building my first app using a couple of books.</p>
  
  <p>I have botched some or most connections due to misunderstanding the concept at first, and I think also renaming objects and variables has caused confusion (connections = targets and actions as I understand it).  In Xcode,</p>
  
  <ol>
  <li>is there a way to remove/clear all these at once?</li>
  <li>is there a tool to find the orphaned objects (ones that still need either a target or action)?</li>
  <li>is there a tool to summarize all of them?  They don't really appear in raw code any place, right?  They are embedded in the .xib if I understand correctly.</li>
  </ol>
  
  <p>I'm on OSX 10.7.2 and Xcode 4.2.1  Thanks!</p>
