Added Oracle Linux 5.9 Box & Updated 6.3 Box to 6.4

Changes

* Updated Oracle Linux 6.3 x86_64 box to 6.4
* Added Provider information to align with upstream master
* Updated src URL to point to the new Git repository
* Added a newly build (4 months ago) Oracle Linux 5.9 x86_64 box

BTW: I closed the Pull Request #150 as I encountered some issues when trying to do `git rebase` on latest upstream master.
