Auto-complete username for review/cc fields in the push to Gerrit window

[geirgp]

When pushing to gerrit I want to specify reviewers and people to cc. This is already possible, but you have to know the exact username of the person you want to add as reviewer or cc. Most of the time I end up not specifying these fields when I push to Gerrit, and instead log into gerrit web, find my change, add reviewers/cc (Gerrit web has autocomplete on these fields)

Would be very nice if these fields also had autocomplete in the Gerrit plugin, so I would have to do the extra step of opening Gerrit web after pushing.
