www.bdsmlibrary.com - Calibre crashes on missing author

[albyofdoom]

There are some stories on the site that are missing the author metadata. When attempting to download these, calibre fully exits with no warning or feedback when attempting to download metadata.

Examples:
https://www.bdsmlibrary.com/stories/story.php?storyid=5028
https://www.bdsmlibrary.com/stories/story.php?storyid=5029

Oh my. It actually flat out calls sys.exit() in the adapter. And that's been in the code for 5 years. That's not good...

Instead of adapter_bdsmlibrarycom.py running it's own re-try loop 20 times (which doesn't work anyway because use_basic_cache:true is on by default), I'm going to change it to set author to Anonymous when none is found.
