importProfile / test case templates

 I noticed the change to the TestCase template to display the importProfile
attribute on the wiki display of a test case, and I'm not sure that's what
we want. The value of this attribute isn't being used to generate the XML
version of the test cases, but rather the profile(s) from the import
directive in the PS is, and the corresponding documentation is here [1].
