ref-filter: add short modifier to 'tree' atom

Browse Source 
Sometimes while using 'tree' atom, user might want to see abbrev hash
instead of full 40 character hash.

Just like 'objectname', it might be convenient for users to have the
`:short` and `:short=<length>` option for printing 'tree' hash.

Let's introduce `short` option to 'tree' atom.
