Fix Popcorn demo RangeControler bug

Added a swap method in the RangeController (very similar to its splice
method). This fixes an issue where the Popcorn demo was not selecting
the first movie on load.
Removed console logs and fixed tabs
Fixed tabs again
Rewrote RangeController.splice in terms of swap and renamed one of swap's arguments

RangeController.splice might not be necessary
Removed RangeController.splice (unused)
Allows to disable a selection when a user move its pointer (finger, mouse…) after having begin to select an iteration.
Allows an iteration to become active after a certain delay.
Which allows us to scroll the repetition without making any iteration active.
Make sure the future selected Iteration is also the current active Iteration.
Set the delay before an Iteration becomes active to 60.
