Implement a sample WSGI Apache config which serves the json-test dir.

If you want to serve other things on a box where you don't control Apache, use dxr-serve.

* Disable the 000-default vhost so ours can kick in.
* Install mod_wsgi.
* Make dxr package installation actually work in puppet.
Stop exporting LD_LIBRARY_PATH in .bashrc.

We're going to start installing the library properly on the Vagrant box. We need to so that Apache's WSGI children will see it. For people not using the Vagrant box, we set LD_LIBRARY_CONFIG in the makefiles during tests.
Install libtrilite globally on the Vagrant box.

This lets Apache's WSGI processes see it.
Stop generating .htaccess files.

Those are really, really clumsy (impossible?) to get working with WSGI. Also, they're not great for performance. If you're going to put a production deployment, it's not a bad assumption that you also control the web server and can put in global config. If you're just booting up DXR to play around, you can use dxr-serve.
Get rid of the --server arg to dxr-build.

We no longer generate any Python code, so this option has little use anymore.

Merge create_server() (whose name no longer at all describes what it does) with its calling function. Someday I'll refactor this whole script.
Bring documentation up to date with the horrors I have wrought.
