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".

Added highlight colours to diff rows

Note form

A lot of the forms have the same actions associated with them so I have created a standard class that encapsulate these actions.

There is also another class that allows toolbar action buttons to be added that will insert different characters based on the HTML `data-prefix` attribute value - this will give us the opportunity to add more actions to the form and maybe create a markdown toolbar in the future.

Fix trailing slash in teamcity_url

Originally opened at !2309 by @ctmay4.

As described in #3515, if you have trailing spaces in the the Teamcity server name, the service
will not work properly.  Switching from `URI.parse` to `URI.join` fixes it so that it works with
or without a trailing slash.

Fixes #3515.
