"destroy" signal handler for any button that pops up a filter; if the button has a filter dialog box associated with it, it destroys that dialog box. Have the routines that create filter dialog boxes asociate the dialog box with the button that created it, so that if the button is destroyed the filter dialog box can be destroyed as well, and associate the button with the dialog box. This means that if a dialog box has a button to create a filter, we no longer have to have the destroy handler for the dialog box destroy any filters - that'll happen when the button in the dialog box is destroyed as part of the process of destroying the dialog box. Don't make the "Filter" buttons in the io_stat dialog box insensitive if there's already a filter dialog box open - we can have more than one open per dialog box. svn path=/trunk/; revision=6930
