re-enable deep version inheritance

[matthias-reis]

Some versions ago, the single step inheritance of versions has been introduced in favor of the deep inheritance. So only direct dependencies have been updated, not dependencies of dependencies.

This feature should be reintroduced as an option, which can be enabled by config:

package.json

{
  "rlsr": {
    "deepInheritanceEnabled": true 
  }
}

Default is false.
Triggers a minor update.
