identifies situations where its restricted by open_basedir.
We now track more informatoin about the toolkit including the version
and any errors we encountered while doing the detection so that we can
provide more info downstream. This makes graphics::detect_toolkits()
a little heavier, but that's ok because it should not be called very
often.
In the process, refactor the controller and view hierarchy so that
it's a little more straightforward in the code.
Fixes ticket #616.
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.
