Include parent properties when doing late replacement of argLine

[basil]

When doing late replacement of properties in argLine, the Maven plugin correctly considers properties defined in the POM, but it fails to consider properties defined in the parent POM. This PR corrects the problem by consulting the model for such properties. The included test case fails without the changes to plugins/maven/src/main with this stack trace:

junit.framework.AssertionFailedError: 
Expected :[-ea, module.value, parent.value]
Actual   :[-ea, module.value, @{parentProp}]
	at junit.framework.Assert.fail(Assert.java:57)
	at junit.framework.Assert.failNotEquals(Assert.java:329)
	at junit.framework.Assert.assertEquals(Assert.java:78)
	at junit.framework.Assert.assertEquals(Assert.java:86)
	at junit.framework.TestCase.assertEquals(TestCase.java:253)
	at org.jetbrains.idea.maven.execution.MavenJUnitPatcherTest.ArgLineLateReplacementParentProperty(MavenJUnitPatcherTest.java:397)

With the changes to plugins/maven/src/main, the test passes.
