Add rails_icons (Tabler) for SVG iconography

Vendors the Tabler outline/filled icon sets via rails_icons' sync
mechanism rather than a hand-rolled SVG set or a webfont -- this app
had no icon system of any kind before. Icons are committed like any
other static asset; re-syncing is only needed when adding an icon
that isn't vendored yet, via the new `make sync_icons` target.
