redo how crossScalaVersions works the old scheme was: run tests on openjdk7 too, but only publish (for all Scala versions) from openjdk6 this is no longer appropriate now that Scala 2.12.0-M2 requires Java 8. now we want to publish for older Scala versions using JDK 6, but newer versions (M2 and above) using JDK 8. this commit does that. currently Travis doesn't offer OpenJDK 8, so we use Oracle. leaving our JDK 6 setting as "openjdk6" since that's what it's historically been so why rock the boat. what happened to running tests on JDK 7? well, neither Lukas nor I knows why it was even doing that.
