add in-line code blocks to paragraph text

Hello, I want to learn/help out with Phoenix framework, so I thought I'd start with the guides, checking them as a newbie, and hopefully adding new guides in the future.

I added inline code blocks `` around files, directories, module action and method names when they occur in the paragraph.
Also tried to add explicit links to localhost uri's so I can click on them from the document, but they are still not made into links, like the external URI's.
Also changed the web/views.ex markup to web/view.ex to reflect the first problem I had in trying the hello app on my local system.

I'm still having problem with getting this hello app to run,
What information is useful in debugging these errors.
I cloned the latest phoenix repo, and below is the versions for mix, and Elixir.

```
➜  hello_phoenix git:(master) mix --version
Mix 1.0.2
➜  hello_phoenix git:(master) iex --version
Erlang/OTP 17 [erts-6.2] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Elixir 1.0.2
```
I also thought it may help to put some version info on the default `/` route that shows the phoenix version easily, but this may be an issue for the framework.

Any suggestions on where additional help is needed would be welcome.
I'll start looking at the enhancements in the issues tab, after I've gone through all the existing pages and gotten them working.

Thanks;
  Kurt
