Remove support for "autoload.exclude-from-files"

This non-standard use of the "autoloads" property should never have been supported.

Changed:
- Example in README to use "extra.exclude…"

Removed:
- Deprecation notice and processing of "autoload" in `ExcludeFilePluginTest::getExcludedFiles()`
- Test of "autoload" in `ExcludeFilePluginTest`

Closes #8
