[PR] Update Salt Bootstrap script to 2014.10.30

* [x] Update the bootstrap script to 2014.10.30
* [x] At least one thing is broken with WSUWP provisioning when updating this script.
* [x] EPEL repo is broken in CentOS 6.x because of SSL 3.0. I had to modify `Vagrantfile` at the project level to get around this. Should be documented.
