Fix crash on using Browse buttons in Tournament dialog Xaw

The Xaw file browser assumes the text entries it is browsing for are
all in dialogs of the class TransienDlg, but the Tournament Options
dialog has been altered to MasterDlg, to allow it to co-exist with
Time Control and Common-Engine dialog (which can be opened through
buttons in it). Xaw did not like that, and the true DialogClass is
now used when setting the widget text.
