mostly issues around uninitialized variables, calling non-static
functions in a static context, calling Session functions directly
instead of on its singleton, passing non-variables by reference, and
subclasses not using the same interface as the parent class.
1) Controller::$input is gone -- use Input::instance() now
2) Handle new 'database.<default>.connection.params' parameter
3) Handle new 'cache.<default>.prefix' parameter
Kohana makes this type of transition fairly straightforward in that
all controllers/helpers/etc are still located in the cascading
filesystem without any extra effort, except that I've temporarily
added a hack to force modules/gallery into the module path.
Rename what's left of "core" to be "application" so that it conforms
more closely to the Kohana standard (basically, just
application/config/config.php which is the minimal thing that you need
in the application directory)
There's still considerable work left to be done here.
