Introduce Vagrantfile

Brings over the Vagrantfile from WSUWP Environment as a starting point.

History can be viewed at https://github.com/washingtonstateuniversity/WSUWP-Environment
Change IP address to 10.10.50.50

This avoids accidental conflict with the IP used by WSU Web Serverbase, inherited from WSUWP Environment
Update header information in Vagrantfile
Remove machine_exists check

This was only necessary when there were issues with mounting and unmounting drives. Now that permissions are assigned by UID and GID, this is no longer used
Correct IP documentation
Correct yet another IP address to match new requirement
Mount this project's working directory as /var/www inside the VM
Temporarily disable Salt provisioning

See the comment on #18 in regards to using shell scripting to 'deploy' provisioning to the virtual machine as if it was a production server.
Add basic proof of concept for inline shell scripts for provisioning

The next step will be to install salt via the bootstrap included with WSU Web Serverbase and then make sure salt is aware of the proper config files
Add .vagrant directory to .gitignore
Merge multiple inline scripts to one script block

This combined script block will be used to retrieve provisioning and initiate the process on the Vagrant box.
Launch the Salt bootstrap file during Vagrant provisioning
Clone serverbase repository into serverbase rather than salt

This will allow for a more sensical file_root in wsuwp-vagrant.conf
s/salt/serverbase/ in directory structure
Copy minion configuration and initiate the salt highstate process
Set salt-call log level to debug
Copy over yum configuration before provisioning
Remove unused Salt provisioning block in Vagrantfile

We're now using shell provisioning to pull in our salt configuration rather than having Vagrant handle this process for us
Download serverbase with curl to remove the initial git requirement

Note: this is broken at the moment. Committing to make a `git blame` easier
Correct syntax for SCRIPT variable storage
