LKSL.Math.Time.pas:
		- Added function "TimeUnitConvert" which takes an input value, an input unit type, and converts it to the
		  output unit type, returning the converted value.
		- Added "<TimeUnit>ToBest" procedures (and overloaded functions returning record TLKTime)
			- These allow your program to automatically determine the best Time Unit (and its value) for a given value and unit.
			- SecondstoBest(0.95, LValue, LUnit); would result in LValue (a variable of type LKFloat) becoming 950, and LUnit
			  (a variable of type TLKTimeUnit) becoming tuMillisecond.
