Stub out class listings
Basic structure of classes is (I think) working.

Redo output of classes JSON, and try to make names more consistent.

Rearrange routes to not fire two AJAX requests at once.

Delete spurious collapse call from talent type routes; I think it was left
over from a very early version of the site.

Add logic for "fixing up" classes - index by HTML ID, replace lists of IDs
with references to actual objects, etc.
Initial description output
Prettier HTML output
Cosmetic tweaks
Split Handlebars templates into separate files.

Update Makefile and Readme accordingly. Update to latest Handlebars.  Switch
to runtime, since compilation is handled on the server.
Set document title

Fix a bug in tip.util.tstringToHtml.
Add class images

Add homepage. Still need top-level nav.

I'm not entirely happy with the style, but it at least works.

Also implement minimal error handling.
