CLIMATE-370 - Update Easy OCW

This is an initial reworking of easy-ocw. Simple bash scripts are being used in lieu of buildout. Now that the dependencies are much easier to install, the added complexity of buildout isn't really necessary. There are still quite a few improvements to add to these and I'll be making relevant JIRAs in a bit to track them. These changes should cover fairly basic use cases. The OS X install script has been tested on a 10.9.2 box and 10.8.5 box. The Ubuntu install script has been tested on a clean 12.04 box using Vagrant.
