Docs/CSS fix: Aallow viewport expand to user's preference

This commit removes the "max-width" property of DOM "containers";
Thus letting the viewport to expand to fill the available space.

This commit aims to bring pleasure to Docker docs' readers' eyes,
And to make them happy by letting them profit more from their large
monitors. (or use more efficiently their smaller ones).

Docs/CSS: Fix Notes/Warnings blocks' BG colour to improve its state.

Docs' BG was original "#fff" and blocks such as code blocks or
warning-notes blocks were coloured in #F2F2F2.

In order to make it easier to read everything, the BG colour was
changed to #fff. However, the switch missed to convert other blocks'
BG colour.

This commit aims to re-introduce the correct contrast by changing the
BG colour of warning/notes block to #fff.

Docs fix: correct /commit info

Correct documentation for POST /commit to reflect that the container's
configuration is supplied in the request body, and not as a query
parameter.

Also correct a small typo in the example JSON for create container.

Addressed regression of private repository documentation.

This adds back in the references to private repositories and
provides some refactoring to the Working with repositories
documentation including updating references to the "Central"
registry to Docker.io.

It also:

* Fixes some links and references to Central Index
* Fixes anchors in other files to updated titles in Working with Repositories.
* Renamed Central Index in the remaining places.
* Updated terms documentation to reflect Docker.io
* Updated some Docker Index naming to be consistent.
* Updates menu labels and hyperlinks.

Remove obsolete 'bootcamp' project.

It was a nice idea to recruit more maintainers but we never found the
time to do it properly...

I am still interested in any ideas to make it easier to start
contributing!
