Upgrade to FontAwesome 5 (take two) (#6673) * Add missing icons to set * Revert FA5 revert This reverts commit 42572ff * use new SVG syntax in locales * Noscript page changes (remove login button, center "powered by" footer text) * Cast wider net for SVG icons in settings - include any _icon setting for SVG registry (offers better support for plugin settings) - let themes store multiple pipe-delimited icons in a setting - also replaces broken onebox image icon with SVG reference in cooked post processor * interpolate icons in locales * Fix composer whisper icon alignment * Add support for stacked icons * SECURITY: enforce hostname to match discourse hostname This ensures that the hostname rails uses for various helpers always matches the Discourse hostname * load SVG sprite with pre-initializers * FIX: enable caching on SVG sprites * PERF: use JSONP for SVG sprites so they are served from CDN This avoids needing to deal with CORS for loading of the SVG Note, added the svg- prefix to the filename so we can quickly tell in dev tools what the file is * Add missing SVG sprite JSONP script to CSP * Upgrade to FA 5.5.0 * Add support for all FA4.7 icons - adds complete frontend and backend for renamed FA4.7 icons - improves performance of SvgSprite.bundle and SvgSprite.all_icons * Fix group avatar flair preview - adds an endpoint at /svg-sprites/search/:keyword - adds frontend ajax call that pulls icon in avatar flair preview even when it is not in subset * Remove FA 4.7 font files
