WIP: provisional LilyPond output
Merge branch 'devel-christo'
FIX: Use Locally-Hosted JavaScript Files

Our problems with the deployment server were caused by incorrectly
setting ALLOWED_HOSTS *and* how we were trying to use a CDN to host
our JavaScript files. I've removed the CDN, so this works now.

Closes #40
FIX: Add Versions to the CWA GUI

This displays versions of the CWA and VIS Framework, along with links
to the respective GitHub repositories.

Closes #45
Fixed: update settings.py

- change ALLOWED_HOSTS to ['localhost']
- add NOTE about MEDIA_ROOT
Fixed: Remove Unused django_vis.views.output_score()
Fixed: Allow Downloading Multiple LilyPond Scores

NB: this also breaks all the other output methods, but only temporarily!

Closes #48
Fixed: Table and Chart Output Now Work with new Directory Structure
Fixed: URLs for Downloading Output Stuff
Increase Version Number (0.99.0 ==> 0.99.1)
Fixed: Remove the Publican "tmp" Directory Content

It was a mistake to commit it in the first place.
Fixed: Additional Formatting for the Deployment Guide

Added proper markup tags to the "Other Things" section and adjusted
content in the "Configure the Web App" section.
Fixed: Update Copyright Year in Deployment Guide
Fixed: Add Markup for "Configure CWA with Apache" in Depl. Guide
Fixed: Update the VIS Framework Install Instructions in Deployment Guide

This accounts for vis-framework being available on the PyPI. Also better
explains the dependencies.
Fixed: (Depl. Guide) Add XML "id" Attributes for all Sections
New: Amend wsgi.py for Use with Virtualenv and Deployment

Previously, these lines appeared only in the Deployment Guide because
they interfere with regular testing. Now they're here too, though
currently commented.
New: (Depl Guide) Add Instructions for Virtualenv Deployment
Fixed: Remove "publican-VIS" overrides.cfg File

It caused problems when the publican theme was installed. It was just an
empty file anyway, so now it's gone.
New: Change the "Depl Guide" to Build with the "VIS" Theme
