Staged Hook

The BeEF hook should be staged; loading only the minimum required functionality to identify the browser and its supported functionality. Then load the appropriate libraries and attempt to load additional libraries where possible.

No files or tests are named. Start by tracing the current BeEF hook bootstrap and library-loading path, then determine how browser identification and supported functionality should select required and optional libraries. Done means the hook loads minimum functionality first, conditionally loads additional libraries, and has checks for the staged behavior.
