Version and Build numbers with maven

New Version and Build numbers can now be given easily by changing the pm4j.buildnumber property in the parent pom.xml.

This file is in the root folder.

Please do not change the Parent Version numbers in parent pom and in the modules. The Parent Pom versioning does not contain the build number. It is looking like the following

pm4j-main-0.4-SNAPSHOT

The submodules version number are given by pm4j.versionning

pm4j-core-0.4.001-SNAPSHOT pm4j-common-0.4.001-SNAPSHOT ...
