vim -- go configuration without symlinks
vim -- Dropped symlink for builtin snippets
vim -- Handle UltiSnips with the runtime path, not with symlinks
README moved in the right dir
vim -- Handle PyFlakes without symlinks
vim -- UltiSnips back to 2.2

Now it's working ok. I should have sorted out dropping the symlinks
mess.
vim -- submodules moved into .vim/bundles
vim -- dropped stale commit for stuff fixed in yankring
