Webpack.js.org: AutomaticPrefetchPlugin not documented

[Legends]

I cannot see the AutomaticPrefetchPlugin under plugins.
If it is very similar to the PrefetchPlugin we can add it there, create a separate menu entry and deep link it...

@sokra by looking at plugin code it seems that it will do prefetch to all NormalModules after compilation was done, can you provide any additional context/info we might add to docs for that?

[sokra]

prefetch comes with two meanings in webpack:

• (web) prefetch: adding a prefetch <link> tag.
• (build) prefetch: discovering a module in the graph earlier to start building these module (and dependencies) earlier (in parallel).

This is about (build) prefetch. The PrefetchPlugin discovers a single module earlier. The AutomaticPrefetchPlugin discovers all modules from the previous compilation earlier when watching.

May or may not have a performance benefit. I guess it's not that important considering that the incremental build times are pretty fast anyway.
