Updated the Vagrantfile to set RAM to 2GB w/2 virtual CPU's

The default VirtualBox configuration is 512MB w/1 virtual CPU.

I was running into insufficient memory problems but quadrupling the
memory and doubling the virtual CPU's should be sufficient without over
taxing low-horsepower contributors.
