Alter behaviour of --skip-dl to allow DRM licensing

Browse Source 
Most people used --skip-dl just to license the DRM pre-v1.3.0. Which makes sense, --skip-dl is otherwise a pointless feature. I've fixed it so that --skip-dl worked like before, allowing license calls, while still supporting the new per-segment features post-v1.3.0.

Fixes #37
