Remove unused classes from Scaladoc

Several elements of the old Scaladoc are not in use anymore. To help
with any reverting, the removal of these is done in a single commit
(this one).

The removal includes:

- Old `Index`, the old top "index.html"
- The letter index (with "_" and "deprecated")
- The old `Template` which is superceded by `Entity`
