games/cataclysm-dda: Complete flavorize and cleanup

- Complete full flavorize
- Cleanup by removing some unneeded USES items
- Use better cmake option helpers
- Add conflicts between flavors (there is no possible to install both
  flavors at same time)
- DOCS and NLS options are available to both flavors
- Bump PORTREVISION
