Some tweaks to the getting started article

Will resolve #85.

I removed most of the references to `psc` as well as fixing the docs
link, as we don't really talk about `psc` in the article anymore since
Pulp is handling all the arguments and options when building.

 Welcome to the PureScript community blog! In this first post, I'm going to walk through the basics of getting set up to use the PureScript compiler `psc`, and its interactive mode `psci`.

 #### Installing the Compiler
 
 You'll need [Node.js and npm](https://docs.npmjs.com/getting-started/installing-node) and to be [able to install global packages](https://docs.npmjs.com/getting-started/fixing-npm-permissions#option-1-change-the-permission-to-npm-s-default-directory) to proceed.

-That's all for this post. We've seen how to use enough of the basics of `psc` and PSCi to compile, execute and test simple PureScript programs. If you would like more information, the [PureScript documentation](http://docs.purescript.org) lists all of the options for both `psc` and `psci`.
