Unit Tests Sensitive to Platform-specific Line Endings

Ideally, 'lein test' should work out-of-the-box for new korma users.  As it is, Windows users have to try and convince the JVM to use "\n" instead of "\r\n".  I believe the Java system property 'line.separator' is what controls this. It can be set from the java command line.or via the :jvm-opts key in the leiningen project file.

Editing my project file to add the line below worked for me
```
:jvm-opts ["-Dline.separator=\n"]
```

This is a very minor issue, but a nuisance nontheless.  Thank you.
