Fix parsing datetimes with timezone not specified

[spicefather]

Some books include datetimes in their metadata without a timezone specified, causing the plugin to fail to download them with the following log:

Traceback (most recent call last):
  File "calibre\gui2\threaded_jobs.py", line 82, in start_work
  File "calibre_plugins.overdrive_libby.ebook_download", line 59, in __call__
  File "calibre_plugins.overdrive_libby.download", line 253, in add
  File "calibre_plugins.overdrive_libby.download", line 97, in update_metadata
  File "calibre_plugins.overdrive_libby.libby.client", line 337, in parse_datetime
ValueError: time data '2009-10-13T00:00:00' does not match known formats ('%Y-%m-%dT%H:%M:%SZ', '%Y-%m-%dT%H:%M:%S.%fZ', '%Y-%m-%dT%H:%M:%S%z', '%Y-%m-%dT%H:%M:%S.%f%z', '%m/%d/%Y')

This change allows parsing these datetimes as though they are UTC.

Hi, I need this fix, can you kindly show me how I can implement this in my plugin or how do I download your version? Thanks so much before.

The "plugin" is just a zip file containing the contents of the repo's calibre-plugin folder. Just download my repo and zip that folder up into OverDrive Libby.zip. Put that into your Calibre plugins folder -- for me, %APPDATA%\Calibre\plugins -- and overwrite the old version.

Seems like you might be using the repo zip directly, you do need to unzip that and re-zip it as noted in my comment above. Once unzipped, go into the calibre-plugin folder, select everything, and create zip (7-zip or Windows' "Send to > Compressed folder" should both be fine).

Thanks finally managed to make it work. Hopefully @ping would come by soon and implement the fix.
