Expand Reference to include .properties and .yml

[timtebeek]

What problem are you trying to solve?

Type references can occur in more places; for instance as value in a properties file, or as value or even key in yaml files.

Describe the solution you'd like

Expand the recently added Reference and SourceFileWIthReferences to also cover properties and yaml. For Yaml specifically it would be nice to also cover cases where the type might be a key, and not just a value.

recipeList:
  - org.....MyRecipe:
      with: arg

For properties only looking at values is likely enough.
