Add test-session-level features for raw unittest framework: * Support --snapshot-update command line option * Issue "SnapshotTest summary" at end of test run * Remove unused snapshots when in update mode This also adds snapshottest-augmented versions of the various ways to run unittest: * `python -m snapshottest ...` parallels `python -m unittest ...` (via module-level `__main__.py`). * `snapshottest.main()` wraps `unittest.main()`. * `SnapshotTestRunnerMixin` can be used with other unittest TestRunner classes.

This also adds snapshottest-augmented versions of the various
ways to run unittest:
python -m snapshottest ...parallelspython -m unittest ...(via module-level
__main__.py).snapshottest.main()wrapsunittest.main().SnapshotTestRunnerMixincan be used with other unittestTestRunner classes.
Closes #51
Still need to:
(is it weird that the module-level
__main__.pywould beused for unittest-specific features?)
only writes files if the snapshot data has changed, affecting
all of nose/django/unittest, but not pytest (and apparently
pre-dating this PR)
