helpers: add a material like slider

This is based upon this work over here;
https://github.com/navasmdc/MaterialDesignLibrary/blob/master/MaterialDesign/src/com/gc/materialdesign/views/Slider.java

It contains my usual fixes for a better memory management.
Also the color control dialog - which uses it by default -
got a few fixes here and there, mostly to make the interactive
shell work correctly.
