there are actually args passed through to prevent overwriting with null
args if they're passed
MINOR Added __get alias to remove need for explicit ->get() call
MINOR Added the injector instance as an object that can be injected into other classes
BUGFIX Fixed issue described in http://open.silverstripe.org/ticket/7448 whereby using the injector to create an object of a type already registered as a singleton would actually overwrite the stored singleton object
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
BUGFIX: Provide default constructor values for classes (fixes issues when used in 'singleton' scenario during dev/build in particular)
MINOR Clear out injector state when resetting db schema during tests (a follow on from changing singleton() calls to use the injector underneath)
API CHANGE: Pass Object::create() calls to Injector::create().
API CHANGE: Add "RequestProcessor" injection point in Director, that Director will call preRequest() and postRequest() on.
