Custom test runner

If args or options, we run the testsuite as quickly as possible.

If args but no options, we default to using the spec plugin and aborting on
first error/failure.

If options, we ignore defaults and pass options onto Nose.

Examples:

Run all tests (as fast as possible)
$ ./runtests.py

Run all unit tests (using spec output)
$ ./runtests.py tests/unit

Run all checkout unit tests (using spec output)
$ ./runtests.py tests/unit/checkout

Run all tests relating to shipping
$ ./runtests.py --attr=shipping

Re-run failing tests (needs to be run twice to first build the index)
$ ./runtests.py ... --failed

Drop into pdb when a test fails
$ ./runtests.py ... --pdb-failures
