Added client assets update detection
/api/check and /api/token/verify will now pass along v1 version string
if used (when config.cacheControl is used) for both home.js and
dashboard.js to use to compare version strings.
This should help notify users using browsers with a bit more overbearing
caching (generally mobile browsers).

Rebuilt client assets and bumped v1 version string

Slight update to yarn.lock (a small syntax change for node-gyp, idk why)
