BUG: '{' in a string will mess up indentation

[davidnorthetal]

indent/json.vim seems to interpret '{' within a string equally as outside of it, thus it "thinks" that a '{' within a string starts a new json-object,

thus e.g. using autoindentation:

{
    "foo": "{",
        "bar": "qux"
    }

This is still happening.
