DataList had several methods that should act on a copy and return
that copy, but was instead mutating the existing list.
We cant change this behaviour in the 3.0 line for backwards compt.
reasons, but this makes the desired behavior the default, and
makes disabling the mutation in 3.1 easier
It also introduces two new methods to deal with the common pattern
of wanting to modify the underlying dataQuery, which we want to be
able to reliably do in a way that always acts immutably. The main
method of these two is alterDataQuery
MINOR Use injector for creating many many list objects
MINOR Use injector for creating objects from within the DataList
MINOR Use Injector::inst() for creating objects; cannot rely on this->injector being present due to many classes being created with 'new', so use inst() directly
MINOR Remove injector autoset property for now; automatically setting it breaks a few test cases that don't know about it for now, and it's not needed just yet

This allows DataList::create(SiteTree) as equivalent to Object::create(DataList, SiteTree), without
having to have a create() function on DataList.
Required for E_STRICT compliance, as child classes cant override create() if they change the arguments.
DBField::create() is also renamed to DBField::create_field(), as this does not just call the constructor, which all other cases of create() do.

API CHANGE: Deprecated SS_List::getRange() in favour of SS_Limitable::limit().
API CHANGE: Introduce SS_Limitable::limit($limit, $offset = 0) as the only modern way of specifying limits; deprecate all others.
API CHANGE: Simplified state handling so that it's just a key store. Affectors are replaced with GridField_ActionProviders. API CHANGE: Removed GridField state manipulation actions instead opting for GridField_ActionProvider actions.
API CHANGE: Removed support for modifiers that add "body" rows, instead having core support for generating the body rows hardcoded into the GridField.
API CHANGE: Allow modification of columns across the whole GridField with the GridField_ColumnProvider interface.
API CHANGE: Renamed GridField_AlterAction to GridField_Action, and added actionName/args parameters, since it can be used for all actions (including batch actions and row actions)
API CHANGE: Removed GridFieldRow class.
API CHANGE: Add DataList::newObject(), which creates a new object on that DataList.
API CHANGE: RequestHandler::handleRequest() now needs to handle a $model argument, if you override it.
