Decode URI components for nested object keys

[drarmstr]

Resolve a bug where backbone-queryparams will properly URL decode values, but not object keys. For example …#...?key.foo%20bar=eggs%20spam will translate to { “key”: { “foo%20bar”: “eggs spam” } }.

The fix is a simple change in backbone.queryparams.js:

var part = parts[i];

becomes:

var part = decodeURIComponent(parts[i]);

Or would you prefer to use parseParams() instead of decodeURIComponent() directly?
