Use Limiter class in waitForTick (#330)

This uses the existing `Limiter` class (stolen from Metaforce) in `JFWDisplay::waitForTick`.
The limiter also now uses `SDL_DelayPrecise` internally on non-Windows platforms.
On Windows, the existing `NanoSleep` logic is untouched, as it appears to provide a
more stable framerate for the folks testing it on Windows than `SDL_DelayPrecise` does.
On Linux, however, `SDL_DelayPrecise` is plenty accurate.
