This patch improves performance of git deployments.

Currently, vlad deletes and clones the entire git repo from the remote host on each deployment. For large projects with
many remote hosts, this can take several minutes.

This patch performs a `git clone` only on the first deployment. On subsequent deployments, it performs a `git fetch`
and `git reset --hard` to fetch only new changes from the scm host.

It's inspired by the Capistrano "sync" command for the Git strategy
(http://github.com/jamis/capistrano/blob/df0935c4c135207582da343aacdd4cf080fcfed0/lib/capistrano/recipes/deploy/scm/git.
rb#L187) and topfunky's pastie (http://pastie.textmate.org/101838)

Ah, thanks Ryan.

It looks like this is assigned to John Barnette in the vlad category
now.

FYI, I asked Garry Dolley, the author of the current git strategy
for his $0.02.
He thought this patch looked good.

when you don't assign a category OR a person, nobody sees these.
