List alias on help printout
Fallback to lookupCommand when looking up a command for `ember help` (to allow for using aliases)
Also add an `unknownCommand: true` property when lookupCommand() returns unknown
command will always exist, just need to check for unknownCommand
Define printUsageInstructions on UnknownCommand, rather than check in _displayHelpForCommand
Remove var command declaration (failing jshint test)
Add tests
Provide more error information if available
