This solves https://issues.apache.org/jira/browse/MRESOURCES-99.<br/>
BUT:<br/>
This should be done different than defining those properties a second time, cause they have already being defined
in Maven Model Builder (package org.apache.maven.model.interpolation) via BuildTimestampValueSource. But those
can't be found in the context which can be got from the maven core.<br/>
A solution could be to put those values into the context by Maven core so they are accessible everywhere. (I'm
not sure if this is a good idea). Better ideas are always welcome.
<p>
The problem at the moment is that maven core handles usage of properties and replacements in
the model, but does not the resource filtering which needed some of the properties.

@return the new instance with those properties.
