"global" dialog box when "Edit:Filters" is selected, so that the list of filters can be edited, and "filter_browse_cb()", which pops up a dialog box associated with a "Filter:" button and a text entry widget attached to that button, so that a filter can be selected or saved (although it also supports the same editing that the "global" dialog box does). Have "filter_dialog_cb()" connect the window in which the "Filter:" button lives and the filter dialog box, so that: if the window in which the "Filter:" button lives goes away, so does the filter dialog box (as it no longer has a text widget into which it can stuff the selected filter); if the "Filter:" button is clicked when there's already a filter dialog box open, we just reactivate that existing dialog box rather than popping up a new one. Also keep a pointer to the "global" filter dialog box, so that we also arrange that there's only one of them (by reactivating the existing on if "Edit:Filters" is selected when there's already a "global" filter dialog box open). Keep around pointers to the dialog boxes that contain the "Filter:" buttons, so that we can arrange that there be only one of them (that was a side-effect of an earlier attempt at fixing the problems described above, but it's still useful for keeping multiple competing dialog boxes from being open - there's more of that to be done). Make the pointer to the "Open Capture File" dialog box widget static to "file_dlg.c" - nobody outside of "file_dlg.c cares about it. svn path=/trunk/; revision=1774
