Add deploy command for docs

[remear]

@wubot deploy docs 1.52

[mahmoudimus]

can you give me more information on how you actually deploy the docs now? what's the rsync command?

[remear]

From the root docs project directory:

make clean && make all

for host in balanced-www-01 balanced-www-02
do
    time rsync --delete --whole-file --recursive --links --devices -vzPO --no-owner --no-group --perms build/1.1/ deploy@$host:/var/lib/justice/docs/1.1
    time rsync --delete --whole-file --recursive --links --devices -vzPO --no-owner --no-group --perms build/1.0/ deploy@$host:/var/lib/justice/docs/1.0
    time rsync --delete --whole-file --recursive --links --devices -vzPO --no-owner --no-group --perms build/static/ deploy@$host:/var/lib/justice/docs/static
done
