Use cwd / XDG_MUSIC_DIR instead of hard-coded path

[NicoWeio]

I think downloading to the current working directory instead of a hard-coded path would be a more sensible default.
Consider that only German-speaking fellows will have their music directory named Musik.
See master...NicoWeio:download-to-cwd for my changes.

Another option might be environment variables / xdg-user-dir MUSIC.

Thank you for your suggestion!
I will look into it, once i find some time (maybe later this week)

So it seems to come down to calling the xdg-user-dir subprocess

import subprocess
subprocess.check_output(['xdg-user-dir', 'MUSIC'])

which, probably only works on Unix-like systems. A solution for Windows users still has to be found.

For the output path a .config file could come in handy, where the paths and languages to be downloaded can be configured.

Something like this:

BLINKIST_PATH=$HOME/MUSIC
BLINKIST_LANGUAGES=DE,EN

The path to this config file could be ~/.config/dailyblink/dailyblink.conf. A Path for Windows users should still be discussed.

Maybe just environment variables are sufficient too.

Also command like arguments could be implemented to explicitly specify paths like . for cwd

I think 5941218 adressed this issue to some extent.

I'm not sure yet if I will find the time to implement the xdg-user-dir MUSIC approach. If someone would like to do a pull request on this matter, feel free to do so!

Less of a change but add at least an option to sets the directory ManuelSchneid3r@7894a36
