Better NetBeans integration

I have tried opening Anathema in NetBeans and it works like charm. A possible issue is however, that I'm not sure what is the intended character encoding for source files. For the NetBeans integration "UTF-8" would be the best (since "UTF-8" is the default). I'm not sure about other IDEs but I know that Gradle won't tell anyone what the source file encoding is, so they must rely on a default value as well.
