Add support for local base url

[lesleyxyz]

Currently, when you supply a local directory for base_url it gives the following error:

Traceback (most recent call last):
  File "/redacted.py", line 181, in build_html_templates
    inlined = css_inline.inline(f.read(), base_url="/my/css/folder/")
ValueError: relative URL without a base

With base_url file://my/css/folder/ it doesn't throw an error, but doesn't do any inlining

Am I doing something wrong or is this not supported at the moment?

Hi @lesleyxyz

Thank you for opening this issue! Indeed, this one is missing - base_url only works for network stuff. I think we need to support the "file" scheme, so something like this would work (note three slashes for an absolute path):

file:///my/css/folder/

#172 adds support for this

Damn that was quick, thank you so much!

You're very welcome :)

The change is released in 0.8.6

Let me know if it would not work for your use case

Just tested it today and working perfectly, so thank you!
