title: Prevent IntelliJ from adding iml files
body: <p>I'm working with Maven pom files, and I don't wish to source control iml files.
  When I open a project, IntelliJ seems to add some of the iml files it creates to the SVN source control. How can I prevent this?</p>
  
  <p>I have "*.iml" in an "svn:ignore" property on the repository root, but it doesn't seem to prevent IntelliJ from adding the imls.</p>
