[svn] * docs/noffle.conf.5,src/configfile.c,src/filter.h,src/filter.c:
Contrary to the documentation, the action of a filter if not specified
was 'full'. Add a new 'default' action which makes the action that of the
group's subscription mode. Make this the default action, and allow
'default' to be specified explicitly as the action in the filter
definition. Adapted from patch submitted by Mirko Liss. Thanks, Mirko.
* docs/noffle.conf.5: Correct small typo.
