HTMLs are fully recompiled in watch mode when have multi html entries

[exports]

I have a webpack project that has about 30 html pages, use html-webpack-plugin makes the rebuild time increases 400% (1s to 5s). Can we only invoke the child compiler only if related chunks are changed?

me too.
i think this PR should work #802
or use this #797
but for me, I use webpack2 now...

I believe this is still relevant for the current version but it needs some work.
Open for pull requests.
