Suppress task logging for help and version actions

[exogen]

This is very excessive:

$ builder -v
[builder:config:environment] {"cwd":"/Users/brianbeck/Projects/Tests/test-builder-log","dir":"/Users/brianbeck/Projects/Formidable/builder/lib"}
[builder:config] Unable to load config file: .builderrc
[builder:local-detect] Switched to local builder at: /Users/brianbeck/Projects/Tests/test-builder-log/node_modules/builder/bin/builder-core.js
[builder:builder-core:start:15907] Started: version
3.0.0-beta.1
[builder:builder-core:end:15907] Task: version ended normally

...and help would be nicer without the surrounding noise as well. For -v/version this can be overridden with --log-level or --quiet, but you can't do the same with help.

Even though builder runs version and help as tasks like any other, that's an implementation detail and IMO the CLI would be nicer (and much more like other tools) without the noise.

Agreed. We can probably even do this at the args.js level, maybe do log-level critical if not otherwise set from CLI to effectively suppress?
