• Added the following metrics:
  
  • has_known_license_in_source_file
    
  • has_abstract_in_pod
    
  • no_abstract_stub_in_pod
    
• Removed metayml_conforms_spec_current metric.
  
• Supported x_cpants custom META field to tell analyzer to ignore
  some of the metrics (only) when calculating a kwalitee score.
  
• Refactored several Kwalitee files, and internal stash layout has
  changed rather significantly. You might need to modify your
  tools if they happen to depend on the stash directly.
