[hibernate-dev] ORM 5.0 and IntelliJ

Another change with master is that IntelliJ import finally works as far as properly setting up excludes in IntelliJ to not "hide" generated-src. The fact that generated-src is under the $buildDir makes this more complicated than it need to be, but it works. There is currently a minor issue with IntelliJ import in ORM master that I have not yet investigated. It has to do with attempting to set different "jdkName" for the hibernate-java8 module. I reported an issue with IntelliJ, but then it seems to work from my standalone gradle-mixed-jdk project[1] Anyway, just a heads up.. [1] - https://github.com/sebersole/gradle-mixed-jdk
