Adds plugin update_all command to internal commands

[getsource]

Just let me know if you have any suggested changes, and/or would prefer a different command-name/structure.

wp plugin update --all ?

[scribu]

wp plugin update - show the list of available updates
wp plugin update some-plugin - update a single plugin
wp plugin update --all - update all plugins

[getsource]

Sure, can do.
Are you suggesting that wp plugin update should show the same output as wp plugin status (only perhaps with the plugins that have available update only?), or do you have specific a information/format that you'd like to see with the output?

[scribu]

Only the updatable plugins, yes. I guess the list can be yellow, for consistency.

[getsource]

Is this more what you were looking for?

[scribu]

Yep, looks great. Thanks!

[getsource]

Yep, no problem!
