Sharktank - Stochastic Extended

The Stochastic as you know it, but with a lot more features.

Options you can tweak:
* Length of the %K value.
* The smoothing of the %K value.
* The smoothing (called %D) for the smoothed %K value.
* Ability to show the original %K.
* Ability to turn of %D so you can take a look at the original Stochastic as it was created (by turning of the %K).
* Show the price at which the smoothed %K will cross the %D (if possible).
* Show both normal and hidden divergence on %K, smoothed %K or %D.
* Some coloring settings.
