Genius lyrics backend fails on request error

[Kraymer]

Problem

Can't make the genius backend work.

Running this command in verbose (-vv) mode:

$ export BEETS_TEST_LYRICS_SOURCES=1
$ nosetests -s -v test/test_lyrics.py

Led to this problem:

Yep, our source—genius-api.com—seems to be defunct. We can either remove the source or switch to screen-scraping the official genius.com pages.
