Unicode support for swift

[Gabriel Hurley]

The backend stack for swift fully supports unicode, but there are still numerous points on our end where unicode characters break things due to encoding problems and string conversions. We should aim for full unicode support.

    Swift name usage cleanup. Unicode support and slash prohibition.

    Ensures end-to-end support for unicode characters w/ swift in all
    places where cloudfiles supports it. (patch submitted to fix cloudfiles).

    Also makes sure that the forward-slash character is not allowed in
    container or object names since it's a reserved character in swift.

    Fixes bug 889564 and fixes bug 940689.
