rsyslog changes for 2007-08-13

As promised, low activity:

– removed debian subdirectory by request of a debian packager (this is a special
subdir for debian and there is also no point in maintaining it when there
is a debian package available – so I gladly did this)
– improved overall doc quality (some pages were quite old) and linked to
more of the online resources.
– released 1.18.2
