Mac OS X support

[stevendesu]

Eventually the shell setup.sh script should super-intelligently determine the machine it's running on and support all sorts of devices and operating systems... In an ideal world

But obviously the world isn't ideal. I just used Ubuntu for ages and that's all I needed

Now I need to install this on Mac OS X. So let's get it working.

Current output:

The issue will mostly revolve around replacing "apt-get" with "brew", I believe. Although it wouldn't hurt to double-check that there isn't a Mac-specific way to install NodeJS or Python.

[stevendesu]

Command for installing Brew (according to their website):

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

I guess Mac comes pre-installed with Ruby? But not Python?

Actually just double-checked and it comes with Python 2.7.10, so not sure why pip wasn't found. I guess Python doesn't necessarily imply pip.
