Minor tweaks for the new UI on Windows

 * Fixes command line parameters (I use these a lot for debugging.)
 * Allows Ctrl-O -> select to work before logo screen goes away (I use this even more for debugging multiple games.)
 * Fixes some debugger window duplicate/focus/enable state issues.
 * Scales the new UI to 1/2x when zoom = 1.  I prefer zoom = 1 and it's an option, so might as well be usable, right?
