UI: Convert settings window to Utility or Undecorated.

[mbahler]

The settings window should be cleaned up by changing it to a Utility Window which will remove Minimize and Maximize buttons since they are not used.
It could also be changed to Undecorated without any title-bar buttons.

When changes are made in the settings window, and the user clicks "CANCEL", does the software undo the changes they made? If not, does the close button have a similar effect?

"CANCEL" and "CLOSE" both do the same thing, (hide the window).

When changes are made in the settings window, and the user clicks "CANCEL", does the software undo the changes they made? If not, does the close button have a similar effect?

Possibly a bug there. If you make changes in settings window and close it, the changes are not applied, but the changes to the UI e.g."Change drop-down selection" remain.
