Allow short versions of the commands

[jsi]

It can be quite cumbersome to write out all the commands sometimes. For instance:

enonic sandbox create

It should be possible to express all commands with a two letter shortname:

enonic sandbox create -> enonic sb cr
enonic project deploy -> enonic pr dp

etc.

As I keep working with the CLI, I think this idea is just better and better. The CLI commands can get pretty long, and using abbreviations would be very helpful. Also, I notice, this has already been implemented for "help", which can be called with "h". Why don't all top-level commands have one- or two-letter shortcuts? Here is a list of suggestions:
snapshot, sn
dump, d
export, ex
import, im
app, a
repo, r
cms, c
system, sy
auditlog, al
latest, l
vacuum, v
help, h
cloud, cl
sandbox, sb
project, p

FYI: There is a plan to place "xp" commands under an xp keyword (or similar). To differentiate from cloud and project more clearly.
