Give feedback on updating packages not in the project
Update old cli tests for new 'meteor remove' text
Update publish-one-arch test for new 'meteor publish' output
Print release name more prettily in 'meteor update' message.

Instead of "Meteor METEOR@1.0", print "Meteor 1.0".

This change is somewhat untested because in order to test it we need
1. a built release, and 2. installed 'meteor' to point to that built
release.
Merge branch 'meteor-update-ux' into devel
Disallow passing nested objects to Npm.strip.

As you can see, this simplifies the implementation considerably.
Further simplify `NpmDiscards` to perform no additional disk I/O.
Use Console in tools/main.js

The specific issue is the "Could not springboard to release..." message
showing up on the same line as a progress bar. Seems like a good idea to
use Console everywhere in this file anyway.
