First pass at plugin reorganization

- Introduces functions.php and moves general utility functions to this file,
  renamed in the global namespace
- Introduces admin.php, for setting up and controlling the Dashboard interface,
  and moves all admin-specific methods there

Fixes #40
Enqueues admin scripts and styles in admin.php, and changes display callback names
Moves Feed Item storage schema and functions out of rss-import module

Fixes #39
Moves archive_feed_to_display() into feed item class as a static method
Begins moving nominations functionality to its own file
Removes nopriv ajax handlers

All these handlers catch events from the Dashboard, and only logged-in users
can view the dashboard. So the nopriv hooks are superfluous
