The commit [1] introduced the `cache-control` header field with the value
`no-cache`. This enforces any cache to revalidate. Apparently this does
not prohibit *FireFox* from caching the assets. `no-cache, no-store,
must-revalidate` does by prohibiting to even save anything of the
request.

By passing "-modtime 1" flag into go-bindata command it uses the same
unix timestamp (1) for every file in the fake filesystem. Thereby every
execution of "make assets" results in the same asset outputs if the
inputs were the same. This forces us to set the "Cache-Control"
attribute to "no-cache".
* Including glue between Alertmanager server and Elm UI.
