Vim, project specific settings

Hey, I've just been looking for a good plugin that can help me to configure some VIM variables per project.

For example I want `set shiftwidth=2` for my JavaScript project and `set shiftwidth=4` for PHP one.

Turned out no plugin needed.

Just put this to your `.vimrc`:

Now if you put `.vimlocal` file to your project root, it will be sourced and "executed".

`silent!` is using to supress warnings when there is no .vimlocal file in a directory.
