DEV 2.4 Do not cause pop-ups or new windows to appear

Recommendations

• Do not cause pop-up windows to occur unless essential.
• Forgivable usage - links to help information about the underlying page, for example on forms, but:
  • Always provide a warning on the link that a pop-up will result;
  • On the pop-up, always provide an explicit 'close' button;
  • The pop-up should avoid obscuring the original page - make it smaller.
