Allow use of HEAD

[leigh-ols]

Is there a way to programmatically reference the latest save/hash?

In git this would be the equivalent of HEAD

for example:

db export production HEAD /blah/blah/dump.sql

That would be awesome. At the moment it doesn't support anything like this, unfortunately, but it should be possible to add relatively easily. If only I had the time...
