Split "filter_dialog_cb()" into "filter_dialog_cb()", which pops up a "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.

In the process of destroying a filter editing dialog box, we get a selection change event on the list of filters. Unfortunately, this can happen after some other widgets in that dialog box have already been destroyed - including some of the widgets that such a selection change event can change. This sometimes happened when "filter_prefs_delete()" hadn't been called, so the mechanism we had been using, with a Boolean datum attached to the dialog box, set in "filter_prefs_delete()" before we actually destroy the dialog box, wasn't sufficient to keep that from happening. Attach to the top-level window data items containing pointers to the widgets changed when a filter is selected from the list, give each of those widgets their own destroy callbacks, clear the pointer attached to the top-level widget when the widget is destroyed, and don't do anything to the widget when a filter is selected from the list if the pointer for that widget is null, as that means the widget's been destroyed and we *can't* do anything to it. Not all filter editing dialogs created on behalf of a "Filter:" button next to a text entry box should, when you click "OK", activate the text entry box; if the text entry box is part of a dialog box with multiple widgets, the user might not have filled in all of the items in that dialog box, so you shouldn't activate it for them. Add a mechanism by which, when creating a filter editing dialog box, you can specify whether the "OK" button should just fill in the text entry box or should fill it in and also activate it. svn path=/trunk/; revision=2922
