minor: yuidocs fixes, whitespace
minor refactoring / reorganizing
UnsupportedFeatureError
AerisTile: Support future tiles types
SnowDepth Tile: Remove uneeded getTileTimesCallback method
Animation#setSpeed/Timestep: prevent unnecessary anim restarting

- Only restart animation if speed/timestep has changed
TileAnimation: init with most current time

instead of latest time.

If we have future times, we want to start at
the current (actual) time, not at the latest future time.
Animation: timeTolerance option

- Prevent showing layers which are to far removed
  from the current animation time.

- Use case: when showing future animation, layers without
  future times will hide after `timeTolerance` ms
Radar: configure future tile type
MockAnimation: add missing methods
AnimationSync: Wait for all animations to fire a load:times event
minor: yuidoc fix
Configure new future tile layers

- Satellite
- SatelliteGlobal
- Radar
- Winds
MockMapCanvas: Auto clean up after tests
Map#scrollZoom attribute

- makes it possible to disable scroll-to-zoom
  functionality (Google Maps and Leaflet only)
Lightning collection: fix invalid model reference

- Was referencing the `Lightning` model using the same
  variable name as the `Lightning` collection.
AerisApiCollection: Fix duplicate models when fetching with { remove: false }

- See https://github.com/jashkenas/backbone/issues/3147#issuecomment-43108388
  and http://jsfiddle.net/tT2D9/3/
Params: do not require to/from to be date objects

- Allows the use of 'today', 'tomorrow', etc,
  which are valid Aeris API query values
Fire model: use from=today param by default

- The Fire endpoint will return models with the same report id,
  when the fire attributes change over time. This is the intended behavior
  of the AerisApi, but it causes problems with Backbone (which expects
  unique ids from the server)
  The fire models are only updated once per day, so requesting models only
  from today will prevent duplicate ids.
AnimSync example: next/prev buttons change by 15 min
