title: Webstorm never show debug warning when application is running
body: <p>I accidentally clicked "never show warning" checkbox when you start debugging an application when there's a current debug session running. That pop up is very useful for me when I don't know if my application is running already and instead of rebuilding I can just use it.</p>
  
  <p>I've already tried deleting the .WebStorm folder in C:\Users\username\ and uninstalling + reinstalling. I am unable to get the popup to show again.</p>
  
  <p>Is this setting being stored somewhere?</p>
  
  <p>EDIT: I found the exact string.</p>
  
  <pre><code>'application' is single-instance run configuration. Are you sure you want to stop the running one?
  </code></pre>
  
  <p>and the checkbox</p>
  
  <pre><code>Do not show this dialog in the future
  </code></pre>
  
  <p>Seems like a build configuration setting.</p>
