Hierarchy#liveChildren was generating a list of all IDs of all pages
on staging. When a site had lots of pages, this basically killed the
tree.
Fix by adding new versioned mode, stage_unique, which uses a
subselect to only return items from a stage that are in no
other stage.
Without this bugfix, if you had a Page that used to be a SiteTree, and you tried to use Versiond::get_version() or Versioned::get_latest_version() to return the older SiteTree version, nothing would be returned, because the results were being filtered by ClassName. This caused bugs in the history panel for certain combinbations of page classname alteration.
BUGFIX Versioned's constructor doesn't provide suitable defaults. Previously a bug/feature in singleton, where it would pass null,true as params to strong_create, which would then get passed through as params to Versioned's constructor, meant that the code still executed fine (as was set to something that wasn't an array, so the null and true were instead taken as args). The fact that the usage of singleton(Versioned) never really used the classes code, purely for value lookup, meant that this never propagated errors. I've now switched singleton() to use the injector for retrieving values, which means these dud values are no longer passed through
CHANGE Given that Config::inst is an implementation of the singleton pattern itself, I've removed the extra call to singleton(). A side effect of this is that it gets around a possibly nasty circular reference with the dependency injector (which relies on the config object); in future, this dependency structure should really be structured from the DI directly.
MINOR Change singleton and strong_create to use dependency injector

Dont start the session until its actually necessary, which is to say there is a cookie available with the current PHP session name (or a request variable with the session_name() - typically PHPSESSID.) The latter allows for passing session ID through as an alternative to cookies.
static function on Extension classes.
BUGFIX FulltextSearchable didn't pass through arguments, use now
available $args parameter with FulltextSearchable::add_to_class()
BUGFIX Don't create new version on related VirtualPage records in SiteTree->onAfterWrite() when the write was triggered through writeWithoutVersion(). Use a new $_nextWriteWithoutVersion flag replacing the -1 Version number for this purpose (AIR-97)
This solves a bugfix when calling singleton($className)->summaryFields() and Versioned kicks back. It is needed to by the GridField functionality to get default columns to show.
This is due to DataExtension calls ClassName::extraStatics() when calling ::load_extra_statics() statically, we need to pass in class and extension.
API CHANGE: augmentSQL is now passed a DataQuery object from which query parameters can be extracted.
API CHANGE: DataObjectDecorators that manipulate the query can now define augmentDataQueryCreation().
API CHANGE: The container class argument for DataObject::get() is deprecated.
API CHANGE: DataObject::buildSQL() and DataObject::extendedSQL() are deprecated; just use DataObject::get() now.
API CHANGE: DataObject::instance_get() and DataObject::instance_get_one() are deprecated, and can no longer be overloaded.
API CHANGE: DataObject::buildDataObjectSet() is deprecated.
API CHANGE: Cant't call manual manipulation methods on DataList such as insertFirst()
