the ui directory. (Perhaps some other files that would be used by all flavors of Wireshark, for any GUI toolkit or for someting such as ncurses, and not for any command-line tool such as TShark, should be moved there as well.) Shuffle some #includes to put the "ui/XXX.h" includes together. svn path=/trunk/; revision=40529
