Nuance - get some scaffolding up there

Summary:
I updated the wiki too - https://secure.phabricator.com/w/projects/pebkac/ - with what I am thinking right now. Rough plan here is

- next diff:
- implement editors and transactions
- implement "web type" for contact source
- /pebkac/item/new/ will be the entry point for this
- implement "actions" on a contact
- probably some "polish" on the scaffolding laid out here; like "create" permissions maybs
- diffs after that:
- implement "twitter"…
