rename smac optimizer files

For using SMAC in ROAR mode we want to import some smac optimizer files (smac_2_08_00-master.py). Using dashes in module names is highly deprecated and right now we use a hack to import the module. See http://stackoverflow.com/questions/761519/is-it-ok-to-use-dashes-in-python-files-when-trying-to-import-them/762693#762693

Start by locating smac_2_08_00-master.py and the other SMAC optimizer files, then trace the import hack used for ROAR mode. Done means the optimizer filenames no longer use dashes and the ROAR imports work without that hack; the payload does not name a test to run.
