release 2.0.0:
now patr-java-build should be able to completely build projects with
their child projects
the child project compiler should now be complete:
(formally sub project compiler)
the children are now build in topological order.
the the dependencies of all (child-)*children are checked
this is needed to get the correct topological order,
because it is not possbile to build a>b>d, a>c>f, a>b>e.
also the install compiler now replaces the version string
with the used version if a snapshot version is used.
this guarantees that if a snapshot version is used
the correct snapshot time is installed.
i.e. "1-SNAPSHOT" -> "1-SNAPSHOT=2024-11-02T23:59:59,999Z"
