Editorial review of 'What Is ConDep?'

First run through of the front page. 

Just for future reference, you may want to use a tool to auto-wrap your lines at 80 or 100 chars, because as you can see from the diff, it's a bit hard to pick out the changes :sunglasses: 

I tried to standardize some of the capitalizations, and added a few links. Mostly, however, it was just cleaning up some minor punctuation and clarifying a few sentences.

Two things I'm not 100% on:

*  the use of markdown links [text](url) vis anchor tags (<a href='url'>text</a>). Was that because of a bug in the  blog?
* That last section is about Scripts, but that's not been mentioned before, and I didn't find a reference in the other existing doc titles? Is that a synonym for Operations, or a collection of Operations?
Thanks! updated the pull request.
