Add optional test aliases
Add optional test aliases

If a "test_alias" dictionary is found in private_settings.py, it is searched for
aliases of tests for the "-n" option. For example, if the dictionary has this
association:

test_alias = { "basic" : "MBED_A1" }

you'll be able to use "-n basic" instead of "-n MBED_A1".
