Fixes #19

Wow, is someone actually thinking about using this?!?

@puffnfresh The travis build is failing, is that expected?

[charleso]

@puffnfresh Also do you want to be a contributor on the project?

[puffnfresh]

I'm not sure why Travis is failing 😿

[charleso]

@puffnfresh Travis is currently building with 2.10. Worth trying to bump to 2.11?

@charleso as an sbt plugin for 0.13, doesn't it have to use Scala 2.10?

[charleso]

@puffnfresh Managed to reproduce with jdk1.7.0_76 (worked fine with jdk1.8.0_92 though). Does that give you anything to go by?

[charleso]

Right, scalaz 7.3.0-M3 compiled with 1.6 bytecode, but depends on 1.8 classes:

scalaz/scalaz@f148413

Sigh. It's almost ironic. :(

I don't mind if you want to fix the build to use Java 8, or use an older scalaz.
