Support all types of SBF level Drupal Tokens

[DiegoPino]

What?

I started to work on this already. Strawberryfield are different to other built in/Module provided Field types around Drupal. We expose dynamic properties and these in turn expose ItemLists of diverse type of Typed Data core entries.

But also the field itself exposes methods for JMESPATH search, decoded versions, flat versions, etc.

So. What type of Tokens do you people need?

Still a think some core Drupal users might need. The WIP code is still valid. Will tag as 1.6.0
