Feature: Expand aliases

Created by: frippe75

Could be nice to have an option whether or not to auto expand aliases. To save time I usually put an alias for openstack as "o" which means my history looks like o server list o stack list

and so on...

Sometimes I'm sloppy and don't setup my aliases everywhere. So then o server list doesn't really mean something.

Think autoexpanding would make sense as a default but I only gave that thought about 10 sec :-)
