v0.4.0

• Find scripts relative to mkdocs.yml, not current working directory - #17

  So, scripts specified in the config (example below), will now work regardless of where mkdocs is run from.

  Running just mkdocs assumes mkdocs -f mkdocs.yml (current directory).

  But now you can also cd docs; mkdocs -f ../mkdocs.yml or any other combination.

  Example config, just as a reminder, no change here:

  plugins:
    - gen-files:
        scripts:
          - docs/gen_pages.py
