Add a script to allow cherry picking patches from another hg tree

From: Mauro Carvalho Chehab <mchehab@infradead.org>

This script allows cherry picking patches from other mercurial trees. It
identifies the newer patches yet not applied at the current tree and
download they to a temporary dir.

The script works with other local trees, as well as with remote URLs.
