Expose slider() chamfer as parameter

Browse Source 
slider() had a hard-coded chamfer of 2 which does not work well for smaller sliders or sliders with thinner walls.

Similar to other modules (or even rail() from this very file) I added chamfer as a module parameter instead (defaulting to 2 for backwards compatibility).
