Implement an install.sh and VagrantFile

I've created an install.sh and VagrantFile to automate the Roundware Server installation process. Roundware is installed with a Python Virtual Environment and configured for use with Apache and mod_wsgi in daemon mode running as the ubuntu user.

I've attempted to reduce the overall amount of changes compared to the original/existing documentation. There are a number of installation procedures I'd like to discuss further, but it's best to reduce the number of changes per pull request.

You can test it out with:

    git clone https://github.com/eosrei/roundware-server.git
    cd roundware-server
    vagrant up

I've deleted old files related to the manual installation process and using FCGI with Apache to host. They seem unnecessary and like clutter now. 

Note: This pull request will be easier to parse if #74 is merged. It's currently showing 1,465 additions and 399 deletions, but most of that is the (L)GPL files. I'll keep such things as separate branches in the future.
