[PATCH] new dialogs -- dialogs don't close on pressing enter/return

[guest]

The new dialogs created using the system in ticket #1176 do not support pressing the enter/return key to close them as the old popup windows did. This forces the user to use the mouse to manually click the "OK" button.

This can be easily handled by an individual plugin by attaching an onsubmit handler to its form:

  this.dialog.getElementById("inputs").onsubmit = function() {
    self.apply(); // function called when the user clicks the default button
    return false;
  }

See the Abbreviation plugin patch attached to #1176 for an example of a plugin that uses an onsubmit handler as suggested above.
