0.4.0

Added

• @HoconPropertySource annotation. You can use it to load HOCON files to env,
  just like you load *.properties files with Spring's @PropertySource

Changed

• Project is built against SpringBoot 2.2. Dependency still uses provided scope
  so it should not be a problem to use any version you prefer though, as Spring's API is stable
• Hocon dependency bumped to 1.4.0

Fixed

• Empty lists now added to processed properties, so you can override non-empty list with empty.

Kudos to FingolfinTEK for empty list fix and @HoconPropertySource feature!
