Rework Map object (#2760)

Browse Source 
This patch reworks the core of the builtin Map object.

Advantages:
 - Provide sublinear access time for the elements via Lcache and property hashmap
 - This implementation is suitable for the builtin Set object as well

Also add the missing 'forEach' routine for the builtin object as well.
