Timing: Optimize Timestamp Aquisition (#479)

Browse source 
* Timing: Optimize Timestamp Aquisition

Currently, we make use of Environment.TickCount in a number of places. This has some downsides, mainly being that the TickCount is a signed 32-bit integer, and has an effective limit of ~25 days before overflowing and wrapping around. Due to the signed-ness of the value, this also caused issues with negative numbers. This resolves these issues by using a 64-bit tick count obtained from Performance Counters (via the Stopwatch class). This has a beneficial side effect of being significantly more accurate than the TickCount.

* Timing: Rename ElapsedTicks to ElapsedMilliseconds and expose TicksPerX

* Timing: Some style changes

* Timing: Align static variable initialization
