Animation - User defined step

[tdipisa]

The animation step can be defined in animation settings. This causes the animation to not follow the leading layer anymore, but instead increasing the time of the user defined step. This functionality is mutually exclusive with leading layer.

Acceptance criteria

• By default the playback initial mode can be configured using localConfig.json. Also initial step values can be configured. By itself the default values (without any confiuration) should be good to start

• When the user opens the animation settings modal:
  --> if a leading layer is selected, will see the leading layer mode selected, otherwise the user defined.
  --> If the "fixed" mode is on the input box and the dropdown for step are enabled (disabled when leading layer is selected).

  • User should be able to define a number and a unit to animate. (for instance: 10 minutes, 1 hour
  • User can insert in an input box the number (with arrows to increment, decrement, use NumberPicker). Initial value should be 1
  • User can select the time unit he want to animate (default unit day)
    • seconds
    • minutes
    • days
    • weeks
    • years

• When the users clicks on play, the animation starts and the current time (or range) element animates following the user selection

Here how "fixed" switch should interact with selected guide layer :
on -> select guide layer -> off
off -> deselct guide layer -> on
on -> off -> select first available guide layer
off -> on -> deselect guide layer
The "Following" remains because it's about following marker while animating...

@tdipisa I re-wrote this issue because it was misleasing and it could be confused with another one. Please review
