Moved coloredcoinlib/test.py

Converted coloredcoinlib.test into one test case in a new testsuite coloredcoinlib.tests . It's now possible to run all tests using `python -m unittest discover` This will run tests from ecdsa, coloredcoinlib, and ngcccbase. Unfortunately coloredcoinlib.tests.test_coloredcoinlib doesn't do much testing, but it runs without error, which is all the original test did anyways.
