>+ Added data collection for web API statistics, specifically regarding the canvas, font loads, 
>+ screen functions, and navigator functions. All of the code is placed under the compile time flag
>+ ENABLE_WEB_API_STATISTICS. The statistics are stored in a ResourceLoadStatistics object and written
>+ to a plist on disk. Added a new file CanvasLog.h which includes a struct to keep track of HTML5 canvas
>+ element read and writes.
