Configurable color ranges/timings

[Josef37]

Allow the user to configure the different color ranges.

Currently they are hard-coded like this:

	std::vector<Range> JumpDuration_RangeList =
	{
		Range{ 0, 180, &GuiColorFailure },
		Range{ 180, 195, &GuiColorWarning },
		Range{ 195, 225, &GuiColorSuccess },
		Range{ 225, 260, &GuiColorWarning },
		Range{ 260, INT_MAX, &GuiColorFailure }
	};
	int JumpDuration_HighestValue = 300;
	std::vector<Range> DoubleJumpDuration_RangeList =
	{
		Range{ 0, 75, &GuiColorSuccess },
		Range{ 75, 110, &GuiColorWarning },
		Range{ 110, INT_MAX, &GuiColorFailure }
	};
	int DoubleJumpDuration_HighestValue = 130;

Maybe different users would like to be more restrictive/relaxed when it comes to these timings.
Allowing them to be configurable seems like the easiest solution.
