Nth PR on develop branch for easybuild-docs, for N=6


Hi @boegel, @stdweird,

I think the new structure is better visible at this point; can you validate?
Best way to visualise it is this one: http://easybuild-docs.readthedocs.org/en/develop/
However, giving the feedback in github style over here would help it advance faster, I guess...
add a separate code block:

"Once the installation has succeeded, modules will be available for WRF and all of its dependencies::

```
$ module load WRF
$ module list
<output>
```

And then:

"For more information, see the other topics discussed in the documentation"

with a reference to the landing page, contents section?
