Add @{...} property evaluation for the argLine.

[hgschmie]

Replaces expressions @{property-name} in the argLine with the
corresponding properties from the model. This allows late evaluation
of property values when the plugin is executed (as compared to
evaluation when the pom is parsed as is done with ${property-name}
expressions).

This allows other plugins to modify or set properties with the changes
getting picked up by surefire.

Nice feature! And it even comes with an extended documentation. 👍

Would you please also create an issue for this in the Surefire-Jira and link your PR there?
Also, an Integration test is required (a new one or extending an existing one, e.g. the ForkCountIT). If you need some assistance there, let me know.

Thanks,
Andreas

added integration tests. They pass fine for me when running

mvn -Dit.test=ArgLinePropertiesIT clean install

The whole test suite does not work for me on Linux using Java 7-86_64 (it crashes with an OutOfMemoryException), but the current master behaves the same. :-)
