Markdown renderers find it easier to determine
where lists start and end when lists are surrounded
by new lines.

For consistency, also ensure entries in the list
are aligned when they span multipls lines.

For the sake of consistency, removes any extraneous
consecutive blank lines from the doc suite.

Add development documentation on how to generate a list of routes

Sidekiq has to be running too.

This was the only thing using the `sdoc` gem, which was blocking another
gem from updating.

This adds the 2016 emoji as well as support for using SVG images instead of PNGs.

It also fixes a number of incorrectly categorized emoji and other minor issues.

Changelog: https://github.com/jonathanwiesel/gemojione/blob/master/CHANGELOG.md#v301-2016-07-16

For the specific emoji added to the Unicode standard, see: http://emojione.com/releases/2.2.4/

Huge kudos to Jonathan Wiesel (@jonathanwiesel) for his work on the gemojione gem!

Using db:reset ensures existing tables are first dropped. This in turn
ensures that we can drop tables regardless of any foreign key
constraints. While CE currently doesn't have any foreign keys EE defines
the following relation:

    remote_mirrors.project_id -> projects.id

MySQL will complain whenever you try to drop the "projects" table first
even when using "DROP TABLE ... CASCADE".
