Highlight critical utilization on the system page (v0.9.6)

Browse Source 
The Current cell of CPU/RAM/disk used turns orange from 80% of the
total and red from 90%. UiFormats.utilizationClass and the mirrored
utilizationClass in gittally.js apply the same thresholds; unavailable
metrics (n/a) are never highlighted.
