* Updates AngularJS to 1.8.0
* Updates the MaterialUI theme to 1.2.1
* Fixes: #1576
Tested by running the gateway locally, with NATS, Prometheus,
and a gateway port-forwarded from a local KinD cluster.
The UI rendered and the newer files were served. Functions
could be deployed and invoked from the store and CLI.

Tested with Kubernetes on a single-node cluster, metrics
reported as expected. Existing metrics still report.
