Update to new template in Veewee; docs

Part of https://www.pivotaltracker.com/story/show/43191469

Here we're updating to use a new template from veewee; also I make some doc tweaks.

Visual inspection should be acceptable.

If you want to go through the whole process (I don't think it's worth it, but it could be fun :-/), you would need to get into this branch and then follow the README; and then you would need to  rm -fR ~/.vagrant.d/boxes/sl-6.2-carbon, upgrade VirtualBox, re-bundle, and bring up a box for ops-bootstrap with the new URL, which you can see here: https://github.com/IoraHealth/ops-bootstrap/blob/jn-add_cron_to_analytics/vm_configs/master-slave/Vagrantfile
