www/badwolf: import new package

badwolf is a minimalist browser that cares about privacy, it is based on
WebKitGTK and thus also accepts WebKitGTK (and dependencies) flags and
environment variables.

Runtime configuration specific to badwolf will probably get added at a later
release.

- No browser-level tracking, multiple ephemeral isolated sessions per new
  unrelated tabs, JavaScript off by default.
- Small codebase (~1 500 LoC), reuses existing components when available or
  makes it available.
- WebKitGTK native extensions, Interface customizable through CSS.
- Stable User-Interface; The common shortcuts are available (and documented),
  no vi-modal edition or single-key shortcuts are used.
- Dialogs are only used when required, javascript popups open in a
  background tab.
