swap evo-classindex for reflections

There is some bug which prevents the `evo-classindex` annotation listings being generated when I run the tests from inside IntelliJ 12.1.4. On top of that, `evo-classindex` has that issue which forces Eclipse users to go through extra setup to get the project to work.

I've had a look, and the [`reflections` project](https://code.google.com/p/reflections/) seems like it's a lot more established (starred by 469 users on Google Code) compared to `evo` (only 9 stars on GitHub). 

Swapping the libraries out was very simple, and it looks like `reflections` should be very quick because you can limit it to analyse only classes in a specific package.
