The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
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)
