This change will mean that SilverStripe\Control\Controller will look for its
template in templates/SilverStripe/Control/Controller.ss.
In order to preserve some backwards campatibility, non-namespaced classes
can have the templates stored in any template subfolder, but once you
add a namespace to a class, the namespaced path expression will need to
be a subfolder of <module>/templates or themes/<theme>/templates.
Layout and Content templates are stil supported as special template type,
Includes still functions but is a no-op. Other template subfolders should
not be used.
Convert form and Textfield styles to use Bootstrap
Split out btn styles a bit more clearly defined (BEM)
Toolbar modifier to improve spacing for smaller screens
Use bootstrap spacer styles .m-t-1 (margin-top-1 x spacer) instead of custom spacer
Added a few typography helpers
Tab styles continued although they are hidden (used on AssetAdmin editor panel)
Required to support new "compressed" form style in admin/assets
which puts form field labels on their own line (and requires the bootstrap layout styling for this)
* Swap out .Actions class for bootstrap .btn-toolbar
* Converted all south toolbars to use new toolbar component styles, content and preview styles for scrollbars adjusted where required
* More pointers to new build tooling docs in upgrading guide
* Fixed docs references to moved files
We don't want to mandate every module to switch from javascript/ to client/src,
but at the same time shouldn't reference non-existant files and confuse newcomers that way.
* More pointers to new React docs

Ported the additional Controller::doInit() references over the main changelog, and shortened them to avoid too much noise in the 4.0.0 changelog (already way too long!)
1. Separated responsibility of handleAction so that it no longer bootstraps the controller and cleans up after the request is handled.
2. NEW beforeHandleRequest to take responsibility of bootstrapping the controller
3. NEW afterHandleRequest to take responsibility of cleanup for the controller
4. NEW calling init on controllers deprecated in favour of callInit() which takes responsibility of enforcing that "base init" is called and the before and after hooks
5. NEW Added prepareResponse to Controller for dealing with responses from controllers
6. NEW setResponse added to controller for setting response objects on the controller
