Utilise the new features provided by the framework to get richer
interface:
* save buttons that highlight the current state of the page
* minor actions in a drop-up
* embed last publishing and saving information
Moving to another page in the GridField for the root assets folder in AssetAdmin
caused all files to be displayed. This was caused by the functionality that tries
to fix some edge cases for detail view kicked in and didn't filter the list properly.
Fixed by making the edge case detection a little more specific (i.e. checking if
a numeric ID was sent as a request variable).
Introduces a preview window that appears when the screen is wide enough,
removes old preview button, adds a draft-public switch, adds variety of
preview options which are not hooked up yet.
Relies on sapphire's f95fadc84416835302fe6c8448054960b5e7ec65

- Added tests for CMSMain->SiteTreeHints()
https://github.com/silverstripe/sapphire/pull/827 adds some extension points for catching HTTP errors such as 404. This change fixes some issues where httpError() isn't used all the time. Note that the aforementioned pull request will be necessary to ensure that it works properly.
setFolderName expects a folder name relative to the root. Specifying
ASSETS_DIR will create a duplicate folder called "assets", so the
file gets uploaded into "assets/assets". Specifying "/" means the
file will get uploaded into the root instead, which is correct.
Ideally we could do this without session, but pragmatically
we still need it, because of the inflexible routing system,
and because of performance considerations.
Example: The tree is lazy loaded via a generic URL (admin/pages/treeview).
While we could add ?ID=<currentpage> to make the view (more or less) stateless,
it would trigger a full tree reload on every tree navigation action.
Instead, we assume that all "reachable" nodes are already cached,
and simply mark a different one as current. For this to work, we need
shared session state between CMS controllers.

Related to #7740. The sort field gets stale if the current
record is moved in the tree. Since the sort value can't
be altered by interacting with the form, its not required
as a hidden field, either.
