Coordinators weren't registering themselves so didn't work. Fixed.

Copied registration code from facet.js and view.js
Quick and dirty job to get things working; needs cleanup
Added check for "exhibit-dev" argument.  Putting "?exhibit-dev=true"
on the url of the page containing the exhibit will force exhibit to
load the unbundled (and unminified) code for easier debugging, as well
as turn off history.
Modified demos to access exhibit through symbolic link to api
Also, assuming commit from 2013-08-03_coordinator that lets user force
unbundling in a url argument, removed "bundle=false" argument from
script so that bundled version is used by default.
Corrected some comments
Fixed a type that was making database chunk loads too large
Added an html table importer, plus a demo including documentation
