Feature #106: JSON format ride files

Target version: 3.0
Patch Attached: Yes
The gc xml format can be slow to parse, especially for longer rides, JSON provides similar human-readable and machine-interpretable files but are much simpler to parse, leading to performance gains.
The attached patch introduces a reader/writer for JSON format and initial tests indicate that writing is 10x faster, whilst reading is 4x faster.
It is worth noting that the computation of ride metrics when a file is first opened is one of the main reasons for the delay between selecting a ride and the display being updated, this can only get worse over time as more metrics are introduced. We may wish to consider writing pre-computed metrics to the ride file to avoid this step (I have coded this up separately and it makes a SIGNIFICANT improvement to ride list navigation).
Attached patch requires flex/bison, but these are pretty standard tools.
