Kinetic now returns directly the pre-render function
instead of returning the kinetic easing function only.
(thanks @fredj)

Add a frameState property to ol.MapBrowserEvent
so that we will be able to retrieve the current center of the view2d from the
framestate in the dragpan interaction.

Add a removePreRenderFunction method to ol.Map
This will remove the pre-render function from preRenderFunctions_ array if
found.

Add support for kinetic effect while dragging.
Only dragpan interaction is supported for now.
The kinetic effect use the maths below (thx @twpayne):
Rate of decay (number, must be negative) = α
Minimum velocity (pixels/millisecond) = v_min
Initial velocity (pixels/millisecond) = v₀
Velocity at time t (pixels/millisecond) =
α⋅t
v₀⋅ℯ
Distance travelled at time t (pixels) =
⎛ α⋅t ⎞
v₀⋅⎝ℯ - 1⎠
─────────────
α
Duration of animation (milliseconds) =
⎛v_min⎞
log⎜─────⎟
⎝ v₀ ⎠
──────────
α
Total distance travelled (pixels) =
-v₀ + v_min
───────────
α
Easing function =
⎛ α⋅duration⋅t ⎞
v₀⋅⎝ℯ - 1⎠
──────────────────────
-v₀ + v_min
