Touch support: Also added stop globe on touch (if spinning) & Double tap (plus zoom in feature on double tap) implemented.

I created a zoom in animation.
Also I modified the tap delegate, so that it now supports both single and double taps: the user can decide what to do on each callback.
Modified the tap msg sent back to the handler. It not has the property noOfTouches so that the developer knows how many taps the user issued.
Implemented the zoomOnHeight: toPoint: time:]; method.
Also added the zoomInOnDoubleTap property..

The user can now decide wether he wants double tap to zoom in or not.. Default is FALSE so as to not mess with pre-existing projects.

All the user has to do is go in TouchDelegateFixed.m and edit the touchBegan method..

edit: Merged with whily globe develop branch on 4/10/13
