template: add shortest(node) template function

Adds a '{shortest(node)}' template function that results in the shortest hex node
that uniquely identifies the changeset at that time. The minimum length can be
specified as an optional second argument and defaults to 4.

This is useful for producing prettier log output, like so:

@  durham  shortestnode
|  77cf    template: add pad function for padding output
|
o  durham
|  b183    template: add shortestnode keyword
|
o  pierre-yves @
|  6545    backout: add a message after backout that need manual commit
|
| o  durham   manifestcache
|/   93f0    manifest cache
|
| o  durham   catperf
| |  c765    cat: increase perf when catting single files
| |
| o  durham
|/   9c53    changectx: increase perf of walk function
