title: Eclipse tfs: unignore project is disabled
body: <p>I accidentally used the TFS plugin to ignore an entire eclipse project (via right click on the project team->ignore)
  I can't undo that using the team->unignore option since it's disabled (along with almost every other option).</p>
  
  <p>I tried searching for a solution, but I keep getting results that has to do with .tpignore file - which don't exist anywhere on my computer (I searched).</p>
  
  <p>I tried disconnecting the project from TFS server and reconnecting - didn't solve it.</p>
