4.0.0

Added

• Confg::__construct() and Config::load() now accept an optional $prefix parameter. When set the new or loaded config will be nested in a config item with the value of $prefix as the key.
• Added Config::toArray() for returning the entire configuration object as an array

Changed

• Config::get() no longer allows the $key parameter to be null

Removed

• Removed the ability to access config variables via PHP object notation (e.g. $config->database->driver) since it required configuration items be re-cast to Config objects

Fixed

• Fixed possible issue when loading multi-dimensial config files
