Disabling timer

- Disabling the timer by default
- Adding flag to enable/disable paging (disabled by default).  When 
  disabled, the second tap will just launch the next task.
- Updating the initial state to put tasks at specific points on the 
  curve.  This allows us to allocate specific space for the front most
  tasks, as well as the tasks behind it.
- Removing hardware layer config (no devices targeting N depend on it)
- Fixing issue with the header not having the final dim applied when 
  transitioning into recents.
- Fixing issue where the stack range would not be reloaded after docking
  or undocking a task.
