Bump to Beta 0.3.3

All seven places the version is written down: .env, the copy in
install.sh, the four package.json files and the /ui/brand example in the
README.

Deleted devices get a signed 410 revoked with an echo of the request, so
a client can tell a revoked key from a network failure; master-key peers
no longer outlive their devices; API keys can manage master keys.
