Implement functionality for Map performance settings in the Settings modal

[austinbaccus]

Map settings should be changeable to accommodate for computer hardware limitations.

• Refresh rate should be customizable
• Max path points should be customizable

This is especially important for Horizon games when free-roaming, because the path won't be erased when a new lap is started since there are no laps. The program will run into severe performance issues on standard settings when travelling too far in free-roam.
