upgrade Omnibus 1.0 and Vagrant 1.1+

We now use an `omnibus` cookbook that lives in the opscode-cookbooks
organization (and is released to the community site). Vagrant support
has also been removed from the bundle and upgraded to use Vagrant 1.1+
which is now installed system-wide.
Update example omnibus config files for new config format

The Omnibus config file is now `mixlib-config` based.
Projects are now built using the `omnibus` CLI
`Omnibus.root` is now `Omnibus.project_root`
`omnibus` cookbook is now pulled in using Berkshelf

The `omnibus` cookbook has been refactored and lives as a properly
released cookbook (along with it's dependencies) on the community site.
update dna.json files for new attribute naming

https://github.com/opscode-cookbooks/omnibus/blob/master/attributes/default.rb
gitignore some additional build-time tmp assets
trailing whitespace and typos
use a different dna.json file for solaris2 build slaves

The Solaris build slaves use a jenkins/build user of `jenkins` as
`jenkins-node` is too long of a username for Solaris 9!
capitalize windows build user to `Administrator`

The Chef user resource will attempt to create a new user account if the
lowercase `administrator` is used.
change json attribute naming to dna-PLATFORM.json

Call me a pedant but I like natural sort order.
Ensure the installed cert authority is loaded on windows
temporarily point at WIP versions of some upstream cookbooks
Update README with new Omnibus 1.0 usage instructions
Update project definitions to latest version of DSL
