Move FDN-specific classes into own package.

Trying to clean things up to have better organization while dealing
with making fdn settings SIM-specific.

The only thing which changed materially in the classes themselves...

- Rename package names to include ".settings.fdn";
- Putting in required imports (mostly for R and PhoneGlobals).
