Add new filter variables that can be used to categorize a dependency as 'runtime'.
  If not specified or not matched, a 'development' scope is assumed.

To avoid assigned all dependencies to either 'runtime' or 'development' scope,
we leave the current behaviour of assigning no scopes unless the relevant input
parameters are configured.

Using a Regex include filter can be problematic when trying to
_exclude_ a matching entry (or entries).
Adding specific exclude filters matching the current include filters
makes configuration more straightforward.
