Forgot to add the test for the Font payload
Remove array/dict class construction code we never used
Setting the validator is now done in Root, since it'll apply to both
Array and Hash.
We don't need to use Payload::Types anymore
The dictionary tie type will be Tie::Dict, not Tie::Hash
We're serializing dictionaries, not hashes
Added the dictionary type!

* Changelist updated
* VERSIONING and TESTING tracking files updated
* dict test suite created
* number test suite modified to also test dict
* Payload::Tie::Root now loads Payload::Tie::Dict
