* New plugin: remove-html-extension falls back to /foo.html when /foo
isn't found in `jekyll serve` mode.
* New Makefile target: `make preview` runs bundle exec jekyll serve
* Updated site docs to describe installing all required dependencies.
Fully tested using a new install of Ubuntu Server 14.04.1
* Set build server to use `make deployment`
* Create Makefile target for 'deployment' to update dependencies if
necessary
* Set Travis CI to run `make travis`
* Create Makefile target for 'travis' to use additional automation logic
* Require in Makefile that everyone use bundle to remove inconsistencies
* Require in Gemfile that everyone use Jekyll 1.3.*
* Require in Gemfile that everyone use Ruby 2.0.0 (already used by
Travis and most developers)
* Remove workaround _plugin/svg.rb which showed SVG files in `jekyll
serve` (fixed in Jekyll 1.0.0)
* Remove inconsistent file path workarounds in _plugins/autocrossref.rb
and _plugins/inline-template.rb
Uses Ruby html-proofer to check the links. This commit also fixes the
various problems it found, as well as dealing with some of its
non-problem complaints (it doesn't like anchor (a) tags without either
an href, name, or id).
Running HTML proofer takes about 12 minutes on my system (with up to two
threads), during which it prints no text. Travis CI times out after 10
minutes of nothing being written to stdout, so this commit also adds a
background process the Makefile to print a line every minute while make
runs.
* update to modern, supported Ruby 2.0 version
* update gems to current versions using Bundler
* make jekyll configs confirm to current version
* switch deb package dependencies to cross-platform rvm
* ignore bundled dependencies
* some README mods as per @harding + @saivann
