Hook up UI elements for adding Actors and AITs.

Created templates for Actors listing page, Details page, and Dialogs for
adding them.
Hooking up Actor interface.

Actor details page fleshed out a bit more. Ability to do tagging for all
of the major items (except aliases) is up and running. All major UI
features for Details page (bucket list, campaign, tickets,
relationships, objects, screenshots, comments) all seem to be working.
Global search seems to be working as well. There's a placeholder in the
UI for Identifiers on the Actor Details page.

Still need to hook up editing the Name, Aliases, and Identifiers. Also
have the entire interface for adding Identifiers to do.
