Add a MetaflacBackend that computes ReplayGain for FLAC files with metaflac --add-replay-gain and reads the values back with --show-tag. Only FLAC is supported. Includes docs, a changelog entry, and tests.
- Fixes some inconsistencies in spelling in the data files we ship with
the plugin as well as adds some new genres to both files that seem to
be returned often by last.fm.
- For some changes the default aliases feature helps to streamline
inconsistencies that come from last.fm already.
- The default aliases file that ships with beets
- Tests fixes that prove that most of the alias normalization patterns
work as they are supposed to.

`requests_mock` was configured with a fallback matcher to return an
exception on any request. The intent was to have tests fail if any
requests are attempted in tests without matching mocks. This is the
default behavior of `requests_mock`, so no fallback matcher is
necessary. The side-effect of the fallback matcher, removed by this
commit, was that 1) the `NoMockAddress` exception was raised to the
function under test rather than to the test harness and 2) the
`NoMockAddress` exception was not able to be constructed because the
`exc` parameter to `requests_mock.register_uri` does not support
exceptions that require arguments. This behavior is visible in the
following log snippet, taken from an incorrectly-passing test:
```

DEBUG requests_mock.adapter:adapter.py:256 GET https://images.amazon.com/images/P/xxxx.01.LZZZZZZZ.jpg 200

DEBUG beets.fetchart:logging.py:163 error fetching art: NoMockAddress.__init__() missing 1 required positional argument: 'request'
```
The test that emitted these logs passed because the `FetchArt` plugin is
written to handle exceptions raised by art sources, skipping and logging
an error. For the exception to cause a failing test, the default
behavior of `requests_mock` of raising an exception to the test harness
when no matching mock requests can be found must be allowed.

Test whether fetchart is run during the import phase and, specifically,
whether the `fetch_for_asis` setting is honored. Mock boundary is
between `FetchArtPlugin` and `ArtSource`, an already-existing internal
API boundary.
