[TIMOB-2100] Android: Implement minRange and maxRange on Slider

By default minRange = min and maxRange = max. These settings are backward compatible.

During creation of the control, min and max settings are determined first, then minRange and maxRange are checked. If they are out of bounds then they are set to min or max depending on the direction.

Example 1:
min = 0, max = 10
if (minRange < min) minRange = min; if (minRange > max) minRange = max;
if (maxRange > max) maxRange = max; if (maxRange < min) maxRange = min;

This keeps the values sane.

If min or max is changed dynamically, then their range value is set to the new min or max.

Example 2:

slider.min = 12; // minRange will now be 12
slider.max = 14; // maxRange will now be 14

After setting the bounds if you want a new min/max Range you may set them.
