Use send message protocol in cli (#493)

Use cliSendMessage everywhere in CLI

Instead of using waspSays and friends, we use the new cliSendMessage protocol everywhere to
send messages. For convenience we introduce a cliSendMessageC that's lifted to commands.

We handle CommandErrors specially now, and have a special way to display errors (failures) and warnings
with a heading.
