This generalizes the oneway arrow logic for adding SVG markers along a
line. Using that functionality, certain tags get arrows on their
right-hand side, indicating which side is "inside", e.g. the
right-side of a cliff is the lower side.
The list of tags considered to be sided (unless there's a
two_sided=yes tag) is:
- natural=cliff
- natural=coastline
- barrier=retaining_wall
- barrier=kerb
- barrier=guard_rail
- barrier=city_wall
- man_made=embankment
The triangles attempt to be reminiscent of the triangles used for
rendering cliffs on OSM (and elsewhere). The different tags get
different renderings (e.g. colors that match the main way, and
different spacings). In addition, natural=coastline is special-cased
to have blue markers (despite having a green way), to emphasise that
the "inside" of a coastline is the water.

- class the #sidebar itself as collapsed not the #id-container
- the #sidebar is the selection, so just use `selection` instead of
`var sidebar = d3_select('#sidebar');`
(which conflicts with the closure `sidebar()` function)
- have separate functions `expand` `collapse` `toggle` rather than a
`toggle(shouldCollapse)`
- Makes the "Sidebar" toggle button permanent but removes the label
- Did some things to the "Save" button to make it the same width whether there
is a count or not (prevents the buttons from jumping when pressing undo/redo)
- Removes a lot of the floated col rules that aren't used much anymore
- Dragging the sidebar below a minimum size collapses it
- A button in the top toolbar lets you uncollapse the sidebar, complete with icon and tooltip
- Double-clicking the divider toggles the sidebar collapse
- Collapse-toggling is animated
- Selecting a feature or ending an add-feature mode auto-opens the sidebar
- Photoviewer UI has been moved from init.js to photoviewer.js
- The photoviewer now has a slight margin to set it away from the sidebar
- The undo/redo, save, and progress indicator controls are now floated to the right
- The save count has been redesigned to visually integrate with the save button
- When the sidebar is collapsed, the mode buttons are centered
- Full right-to-left layout support for all of the above
