* Remove unused bluecloth gem
Last released in 2011. It was only required, never called; kramdown
renders the markdown.
* Add specs for Tilt markdown rendering and posts markdown partial
* Remove rails_12factor gem
Last released in 2014. Rails 5+ does this via RAILS_SERVE_STATIC_FILES
and RAILS_LOG_TO_STDOUT, which production.rb already reads.
* Remove memcachier gem from Gemfile and Gemfile.lock
* Remove unused webrat gem
Last released in 2011. Nothing requires it; the specs use Rails'
assert_select and Capybara matchers. Only generator comments mention it.
* Remove crowdin-cli gem
Last released in 2018. Crowdin now ships its own standalone CLI, which
reads crowdin.yml and doesn't need the gem. Also drops the dependencies
only it used (rest-client, gli, crowdin-api and friends).
* Removes the crowdin-cli gem (last released 2018), the dependencies only
it needed, and crowdin.yml. Crowdin was never set up: the config still
has a placeholder project ID and nothing else in the repo mentions it.
