Nolan Darilek 7b4fb8dae4 Clean up speech synthesis properties, and implement everything for WinRT.
I'd previously attempted to normalize everything to `u8`, but this had some drawbacks:

 * It failed to account for some synthesis drivers defining normal as mid-range, while most define it very low.
 * It didn't track the normal value for a given synthesizer.
 * There was no clean way to map a curve between the minimum, normal, and maximum rates.

Here we track the minimum, normal, and maximum values of rate, pitch, and volume. Sanity checks are done on set.

Also, as a further proof-of-concept, all properties are now implemented for the WinRT driver.
