webpack plugin compat

A compatibility layer for the webpack plugin API that simplifies supporting both v4 and pre-v4 versions (v3/v2). Current version 1.0.4 adds support for Tapable v2.0. Key differentiators: transparent event name mapping (spaces/hyphens to camelCase), HookMap support via space-delimited tokens, special-cased parser events, and a unified reg/tap API that works across webpack versions. Maintained by the Dojo toolkit team.
