Adding Vagrant capability

Assuming you have vagrantup.com installed, this lets you run "vagrant up" which basically gives you a functioning ThinkUp install running at http://localhost:8080 ready for logging in and configuring.

- Username: vagrant@vagrant.local
- Password: thinkup00

Vagrant steps:
- Builds precise64 box
- Install apache2, MySQL, PHP and extensions
- Create a root mysql user, saves the password in /etc/mysql_root_password
- Runs the build-db_mysql.sql script into the thinkup database it creates
- Adds the default admin user

Developed / tested on:
- OSX 10.7.5
- VirtualBox 4.3.6 r91406
- Vagrant 1.4.3
