Title: speed up tests suite using parallel_tests

https://github.com/grosser/parallel_tests will run tests in parallel in order to seed up a test suite.

For existing and new active_admin developers, this change should be smooth. Running the rake task will rebuild automatically the spec/rails apps.

I am not sure how if travis-CI build will be faster but it shall speed up the tests on development machine with 2 or more cores.

## Benchmarks

Using Rails 3.0.12, I save 1 minute on my machine which is a macbook 2008 (2 cores).

### 1 CPU (current config)

time rake test

real	3m11.588s

### 2 CPUs

time rake parallel_tests

real	2m10.688s
