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)
