Add "lyrics" as a command

[Arsukeey]

I've added the feature to show the lyrics for the song that is currently playing.
However, it adds a dependency: lyricwikia.

Sorry if you don't want more dependencies to your project, but I thought it would be cool to add this feature, because I downloaded your program for it, and I was surprised when I didn't find it.

Hi @Arsukeey.

Thanks for your PR and contribution. It's nice idea and we can add such functionality. Nevertheless, I don't like a few things in the code. I've added my suggestions in the code review. Moreover, please fix code formatting (you can find details in the README.md) because CI is failing and squash your commits into one.

Regards,
Piotr

Thank you for the heads-up, I was changing some variable names for testing and I forgot to remove/rename that.

[pwittchen]

Thanks for the update.

There's still wrong formatting, not updated setup.py file and multiple commits. You can use rebaseandsqua.sh website for that.

[Arsukeey]

Thanks for the website!
I updated the setup.py and the code now complies with pep8.

Thanks,

Can you squash your 8 commits into one? I prefer to have more organized history on git (1 commit / PR). It can be done by rebasing and squashing the commits.

[Arsukeey]

Done! :D
But please test if it works on your computer before merging.

[pwittchen]

Thanks! We're almost there. I have only last small issues with the code. Please, have a look at them. Of course, I'll test it before merge ;-).

[Arsukeey]

Fixed the issues.

When I execute:

./spotifycli/spotifycli.py 

I constantly get:

Traceback (most recent call last):
  File "./spotifycli/spotifycli.py", line 9, in <module>
    import lyricwikia
ImportError: No module named lyricwikia

but I've already installed lyricwikia with pip :(. Maybe something is wrong with my configuration or it work differently in a scripts like that, but I don't know how to fix it.

[Arsukeey]

Have you tried to import it in the terminal? Try to pip uninstall lyricwikia and then remove the leftovers from your ~/.local/lib and /usr/local/lib. Then reinstall it and make sure you're installing for 2.7

Ok, after reinstalling package, it worked :-D.
PR is merged. Moreover, I've removed empty line and added exception handling when lyrics are not found.
