Basic test suite ready

Test suite to test CH actors - first try.

Basic scheme is to spawn a thread (forkIO) with Cloud Haskell operations with the MVar to get reason of failure (Nothing means no failure), wait in main thread for some time, read result MVar without blocking and analyze cases.

It seems that HUnit does not help with Jenkins XML output. At least I haven't found how to combine them out-of-the box.
