Fixing ie support
Updated the flex styles to bias to auto size, rather than 0 size. Since the bias is only used by IE (though part of the standard), this was causing a break in IE but "worked" in current versions of other browsers...for now.
Minimal CSS change to accomplish goal. Also make all terminal windows use same div nesting. This fixes a bug where IE displays the title bar at 0 height for modal dialogs, but OK height for other terminal windows. Not sure exactly why, but just being uniform made it go away, so good enough.
