[platform-ui-dev] Running individual performance tests

[Kim Horne <Kim_Horne@xxxxxxxxxx>]

The UI performance tests currently rely
on the fact that they're run after being wrapped with a UIPerformanceTestSetup
TestSetup object.  As such, attempting to run any given set of tests
outside of the main performance test suite will result in errors (missing
resources, primarily).  In order to run individual test classes I've
checked in org.eclipse.ui.tests.performance.PerformanceTestRunner.  This
class will wrapper the class specified by the "org.eclipse.ui.performance.test"
system property with the appropriate test setup so that it may be run seperate
from the entire test suite.  I'm going ot investigate making this
easier (read: transparant) in the future.
