Kicad intergration bugfix // Kitspace PEP8 cleanup

[miili]

Thanks for this module, but it appears the Kitspace API is down / overloaded atm.

In this PR:

• Fixed an importError in the KiCad module.
• PEP8 the Kitspace module (a little bit), added better log strings.

Easy general suggestsions:

• [x] Use dedicated loggers per module: logger = logging.getLogger('kitspace.partinfo')
• [ ] Rewrite the Kitspace module, maybe use asyncio?

[set-soft]

• The PEP8 part of this patch is already included in #450
• The logger = logging.getLogger('kitspace.partinfo') is a good suggestion. But currently the code uses format='%(message)s' rendering it useless (no severity, no module, no source, no line, etc.

[set-soft]

Now we have some logger separation.
