use the capture filter lists, and others use the display filter list, as appropriate. Have separate menu items for editing the capture and display filter lists. Have separate "~/.ethereal/cfilters" and "~/.ethereal/dfilters" files for the two lists; if either of those files isn't found, we try "~/.ethereal/filters", which means that you will start out with two identical lists holding all your filters - if certain filters belong only in one list, you'll have to delete them by hand from the other list. Do I/O error checking when reading and writing filter lists; when writing a filter list, write it to a new file, and then rename the new file on top of the old file, so that you don't lose your old filter list if, for example, you run out of disk space or disk quota. svn path=/trunk/; revision=2948
