[Slider] [commit 4b1d548] broke smooth: true with preventCrossover: true

[mfeherpataky]

At the moment the DOCS of Fomantic show examples of smoothly repositioned slider.
It however it does not move smoothly, and the slider thumb moves in discreet steps to where the click was registered (even in cases of step: 0).

The root cause is the commit 4b1d548
Commit message says

BREAKING CHANGE: preventCrossover is set to true by default, making this a breaking change.

Current state of affairs: smooth works only when preventCrossover is set to false

Ideas for possible solutions:
(a) handle both smooth: true and preventCrossover: true,
(b) immediately - do not set preventCrossover: true and/or add information to Docs that prevent preventCrossover: true renders smooth: true invalid.

We'll look into this, both settings being true should work together of course
