Implementing namespaces for Kohana Core and later modules

[rjd22]

I'm thinking of opening a new PR on the Kohana core to implement namespaces on all classes and another to move out the Cascading Files to a different repository for backwards compatibility.

This would at least more Kohana Forward to namespacing and make it more compatible to the PSR-4 standards.

I wanted to give a heads-up that I want to do this and was wondering if you people think this would be the right direction to go in.

This will most likely end up in a Kohana 3.5 version since it's mostly backwards compatible.

The discussion in this ticket is related:
#571

@acoulton @enov @lenton @shadowhand would this be appropiate?

👍 would ideally like to see this come with a script to add relevant use statements to end-user code files for quick upgrade.

Hell yes, lack of namespaces is really annoying!

@enov @acoulton @Ikke I started working on this in the following branch. #663

I'm taking small steps so the tests won't fail and the merge will be easier. There are some classes that are hard to convert like the UTF8 class so that might need some more work.

Could you please check this PR to see if it's going into the right direction?

Thanks for the hard work @rjd22.
