Feature: different buffers for running ns tests

[andreyorst]

While working on a big project where I can't run all project tests all of the time, I tend to run tests in specific namespaces. Right now, CIDER creates the *cider-test-report* buffer, which name is hard-coded in the cider-test.el file. It would be nice if CIDER named this buffer something like *cider-test-report: actual.namespace.name* so I could run tests in several namespaces without loosing results between runs. Right now I manually rename these buffers, but it breaks the jumping functionality. If running tests for the whole project, the default *cider-test-report* can be used.

It's a good idea IMO - potentially something we can make configurable. It should be fairly easy to do.
