Capabilities cleanup: make most get*() final, impl. Comparable to CapabilitiesImmutable, Misc ..

- Comparable<CapabilitiesImmutable> to CapabilitiesImmutable:
  "interface CapabilitiesImmutable extends VisualIDHolder, WriteCloneable" ->
  "interface CapabilitiesImmutable extends VisualIDHolder, WriteCloneable, Comparable<CapabilitiesImmutable>"

- CapabilitiesImmutable and GLCapabilitiesImmutable get-methods final (most)

- GLCapabilitiesImmutable.compareTo: add doubleBuffered (between stereo and samples)

Misc:
  - Add @Override
  - remove trailing whitespace,
