Make entry and source directory configurable

[insin]

You shouldn't have to move files around to swap nwb into an existing app for build tooling

Remembering why I hardcoded all the entry points - they end up in 3 different configurations of webpack config (path, object with path, array of entry points) and the same type of command is used twice for different things in one of the project types.

Notes:

Need custom entry for:

  type       command               data needed                            common entry point
  ----       -------               ------------------------------------   ------------------
  app        Serve React App       (path, ends up in an array)            webpackServer()
  app        Build React App       (object - property names the bundle)   webpackBuild()
  app        Serve Web App         (path, ends up in an array)            webpackServer()
  app        Build Web App         (object - property names the bundle)   webpackBuild()
  component  Build Component UMD   (path)                                 webpackBuild()

Separate custom entry for?

  component  Serve Component Demo  (path, ends up in an array)            webpackServer()
  component  Build Component Demo  (object - property names the bundle)   webpackBuild()

Don't need custom entry for:

  Module Build
  Tests

A problem:

  React component modules use `webpackBuild()` twice

Solutions?

  Pass an extra options argument to it?

  `webpackBuild()` - entry from build config passes through to
  `createWebpackConfig()` - looks doable!

Does this solution fix anything else?

   `webpackServer()` - entry is created in `createServerWebpackConfig()`,
   passed to `createWebpackConfig()` - looks doable!

In both cases, we need to know whether or not we're building a demo (to use
a different piece of user config for custom entry?)

New options argument: `options = {demo: false}`?

Of course! Command line arguments!

Sorry for bumping, but has there been any progress on this? Are there any workarounds?
