3.0.0: ObjectOf API

This release brings this library up-to-date by dropping dependencies on archived libraries and adding a more generic object instantation
mechanism not reliant on a certain class architecture.

• Removed dependency on xp-framework/collections library, add a Pair
  class of our own

• Made library compatible with XP 11, dropped XP 9 (and lower versions)
  (@thekid)
• Merged PR #6: Add new util.address.ObjectOf. It replaces the old
  CreationOf API, which requires objects to have a with() method
  returning an InstanceCreation instance

• Merged PR #5: Refactor code base, dropping dependency on the partial
  library
