- Route `/assets` -> `build/public`, falling back on `public`
- Moved destinations for `nodebb.min.js`, `acp.min.js`, `admin.css`, `stylesheet.css`, `templates`, and `sounds` to `build/public`
- r.js modules previously routed through express are now symlinked into `public/build/src/modules`
- minfiles no longer served from a memory cache
- use config `views_dir` setting everywhere template directory is used
- fix cache buster `v=v=`
- Search uses translated titles if available
- Use `advanced` for `development` route titles
- Remove route title from showing up in results
- Highlight matching part of result title
- Don't show empty result contents when only title is matched
removed unnecessary admin checks in src/admin/user then realized they
are just one liners so moved them to src/socket.io.admin.js moved
categories update to categories folder
