- Changed Data::$l to Data::$lang; it's not used enough to justify the possibly confusing shortening
- Made database auto-update a general rather than per-driver setting
- Added settings for forthcoming feed fetching service
- RuntimeData has now been replaced by a single static Data class
- The Data class has a load() method which fills the same role as the constructor of RuntimeData
- The static Lang class is now an instantiable class and is a member of Data
- All tests have been adjusted and pass
- The Exception tests no longer require convoluted workarounds: a simple mock for Data::$l suffices; Lang tests also use a mock to prevent loops now instead of using a workaround
