This adds support for using VMWare Fusion as the Vagrant provider,
which has better performance than Virtualbox at the price of being
nonfree (in all senses of the term).
We haven't done solid benchmarking as to how much faster it is than
the Virtualbox provider.
Updates Zulip dev setup for first-time contributors as follows:
- Recommends and links to Vagrant version 1.8.4 (from 1.8.1)
- Consolidates Ubuntu 14.04 and Ubuntu 16.04 instructions since they are
now identical.
- Updates memory requirement to 2GB to address out of memory related
errors (see issue #1333).
Fixes#1288.
Sphinx/RTD creates different anchor tags for subheadings than
Markdown does, and treats image embedding differently.
This commit updates hyperlinks to affected anchors,
and fixes an image embed for move to RTD.
We aim to consolidate developer documentation on Read The Docs. As a
start, this commit turns the first part of README.dev.md into a topic
page within /docs/ , and links to it from the doc index.
See #669.
