Make specs2 aware of JUnit categories

[martinburger]

We use JUnit categories to group "fast" and "slow" tests. Unfortunately, in the words of Eric Torreborre:

Specs2 indeed doesn't know about Junit categories yet.

See this question of Stack Overflow for further information.

I have just added the Filterable interface on the JUnitRunner, which should filter the specification class based on categories annotations. Unfortunately I can't test it at the moment. Can you please grab specs2-2.4-SNAPSHOT and check if it's working for you?

[etorreborre]

Did you have time to test this?

[martinburger]

I could finally take some time to test this. However, it seems that specs2 still ignores the JUnit category: although I added the category via @Category(Array(classOf[NightlyTestCategory])), Surefire still runs all tests including the actually ignored ones.

Yes, this is a great feature. We added this to junit-interface
