update and remove the "www" files bundled

i made them more specific for docker

Looking nice, is there a link to the Admin?

Are all these extensions installed by default? Can we make some of them optional? Many users don't use any of them, especially in a lean environment like Docker

[zspitzer]

We've already unbundled a lot of extensions in 6.0, what else do you want to chop? For lean and mean you start with light (or zero) and add your desired choices.
