Fix the Redirect warnings from Brakeman

Unfortunately I've had to leave the check disabed as Brakeman
can't see inside the safe_referer method so doesn't realise that
it is cleaning the referer.

Use the worldCopyJump option for leaflet overlays

This means that if you pan to a 'copy' of the world, the overlays
reappear on that copy.

Fixes #2040

Add some changsets that shouldn't be selected

Update to iD v2.18.3

Refactor changeset index testing to assert against objects, not db queries

This avoids the situation where tests pass despite an empty db.

Add a browse map link to notes

This matches the one for nodes. Fixes #1355. Replacement for #1773.

An unstyled list works better for the details section, particularly
when all three are shown.

Use a named path instead of explicit controllers and actions

Use Brakeman for static code analysis

Rephrase 'replying' text to clarify what will actually happen

Fixes #2166

Remove unnecessary css

Images have no border in modern browsers, and bootstrap's reset also
sets this.

Remove unused css

Use bootstrap backgrounds and text utilities for read issue reports

Rename nav-related body classes

This makes it clearer that the classes are only for navigation menu
matters. Other things should be done on media queries, or ideally,
using bootstrap components like grids.

This has a side effect of removing the smaller font size from the
body when the navigation menu is in the small-nav state.

Move the login form rules to be based on screen size

Ideally this would be refactored to be mobile-first, but is likely
to be replaced by more general bootstrap form refactoring anyway.

Remove webkit-appearance: none

This is the default anyway, and we don't need this for anything specific.

Rework the about header size change to be based on the screen width, not the menu state

Also reworks to be mobile-first

Remove dead CSS code - nothing has the user_map class

Remove unnecessary layout calls from api controllers

These were left over from the refactoring of the controllers into api and non-api versions.

Rename the notes#mine action to index

Use bootstrap text-muted in place of custom deemphasze class

This avoids changing anything related to forms, since they will be
switched over to bootstrap separately.

Remove some extraneous css

The trace part is actually removing html, but I thought it was CSS
when I first noticed the blank space on the page.

Rework the users#show page to avoid custom column css

This uses bootstrap instead, ensuring the map shows before the
text on small screens, but to the right of it on md+ widths. The
height of the map also changes at this breakpoint instead of being
based on the menu width (body.small).

The account edit page was also changed to match the content_map
changes, and a full width map is now used. This can be changed, if
required, using bootstrap breakpoints but I like it as it is.

Tuen on turn restriction support for graphhopper
