Maven and build fixes to allow log4j, Chainsaw and companions (minus ZeroConf) to be built without requiring manual installation of any maven depdencies
 - replaced log4j 1.2.16-SNAPSHOT references with log4j 1.2.16
 - added java.net repository information to automatically provide javamail maven dependency (java.net repo provide javamail 1.4.3, so all javamail refs were updated to 1.4.3)
 - added openejb maven dependency information to support javaee class dependencies
 - updated 'version' property to 1.2.16
 - removed zeroconf maven dependency from Chainsaw, added jmdns 1.0 maven dependency

All modules build (including tests) on Fedora 11.
