Confirm Java 7 support

So I got through this error by copying the "build.properties" file into the compiled class directory (target/classes) from the src directory. I'm still having other problems, but at least I can get through this simple bug.

I'm not sure why you would need to copy the file over manually, unless you're only doing an sbt compile in the source directory. Unlike maven, the sbt compile phase doesn't copy the resources into the classes directory. If you're building from source, I recommend you either run sbt package and use the generated jar, or if you really must use the target/classes directory, then run sbt test, to make sure the tests pass in your environment, which will also copy the resources.

Also, if you're building locally just to use the current master code, then you should consider using the 2.2.0-SNAPSHOT versions being published to the Sonatype OSS Snapshots repository.

Finally, for the current issue, I've run all the tests under Java 7 and everything passes. If you have a use case that fails for you under Java 7, please create a new issue.

You have exposed me as the novice that I truly am to Scala, sbt, and the like. Thank you for your suggestions and advice. I will give it a shot. And thank you for your contributions, always.
