* `Url::into_generic_url` was deprecated in 0.4.1. The `Into` trait is
used instead.
* iron/logger removed support for ANSI terminal colors in 0.2.0, which
makes logging work in the Command Prompt on Windows.
Fixes#21
This extracts rustc-serialize JSON serialization into its own module,
decoupling all core structures from its use.
rustc-serialize can now be completely disabled, removing it as a
dependency if serde (or none) is used instead. It is, however, still the
default serializer. In Cargo, the `default-features` field must be set
to `false` to disable it, e.g.,
[dependencies.juniper]
version = "0.6"
default-features = false
features = ["serde"]
The Iron handlers still require rustc-serialize.
The default values for attributes changed from being formatted as JSON
to how it is defined in [the reference implementation][printer.js].

This adds the Serde serialization trait to the following:
* `ExecutionError`
* `GraphQLError`
* `InputValue` (+ deserialization)
* `RuleError`
* `SourcePosition`
* `Spanning<ParseError>`
* `Value`
Serde support is enabled via the "serde" feature flag.
