WIP - getting to 2.11.
Re: #3 enumeration names are no longer supported as constructor arguments for Scala 2.11

Looks like my editor removed trailing whitespace too.
Re: #3 specs2 no longer accepts unit results unless flagged as such.  Dropped Scala 2.9 to avoid supporting older specs2.
Now that 1.3 is published, this PR has become 1.4-SNAPSHOT.
Merge pull request #4 from d6y/2_11

Support for 2.11
