recent changes

A couple of changes the last days. They are all now in cvs. Tomorrow we will release 1.19.10.

– bumped version number
– changed ommsyql to allow for “:ommysql:” module specific action call method
instead of “>”. This shall facilitate the creation of other plugins.
– added notes about new action module designator to module documentation
– updated user doc to new module action calling convention
– updated rsyslogd doc set man page; now in html format
– undid creation of a separate thread for the main loop — this did not
turn out to be needed or useful, so reduce complexity once again.
– added doc fixes provided by Michael Biebl – thanks
