[PATCH] [LIT] Add NativeMetricValue type to wrap types supported by the json encoder.

[Eric Fiselier]

Hi ddunbar,

The following types can be encoded and decoded by the json library:
`dict`, `list`, `tuple`, `str`, `unicode`, `int`, `long`, `float`, `bool`, `NoneType`. 

`NativeMetricValue` can be constructed with any of these types, and used as part of Test.Result.
This patch also adds a toMetricValue function that converts a value into a MetricValue.
