Overview, Troubleshooting, and Permalinks

[codydaig]

In terms of sections of the documentation, Overview and Troubleshooting were the only two that I could tell didn't need any changes to make then applicable to 0.4.0. The remaining sections have some sort of change to make them applicable.

The navbar has been modified to show the link to 0.4.0 when you hover over it. I also changed the doc folder/file structure slightly to allow for permalinks. /docs.html will go to the current (stable) version which is marked 0.3.x in the code.

Lastly, I added permalinks for:
/docs/0.4.x/ which will render the docs for 0.4.x
/docs/0.3.x/ which will render the docs for 0.3.x (which is the current view)

I did this to allow for multiple versions of the docs on the website as the project continues to develop.

This pull request is ready to be merged, however, I am submitting it as a discussion point for the Yo Generator Section and merging this can be delayed. (Which I am bringing up in #443 )

@codydaig is there a way I can visually see the changes that this PR adds?

DO NOT MERGE THIS PULL REQUEST UNTIL I ADD THE CNAME BACK AND MODIFY CONFIG.YML.

gh-pages makes it difficult to test on live sites other than the one you want it published too. If you want to test locally, you have to install jekyll and run jekyll serve from the directory. (I put the install and run commands in the README.md file of the gh-pages branch). So, for these bigger changes, I'll just keep it live on my gh-pages branch until it's ready to be merged.

@ilanbiala @lirantal Thoughts on this structure to differentiate 0.4.x from 0.3.x before I continue adding documentation?

[lirantal]

LGTM
@ilanbiala @rhutchison?

[ilanbiala]

I think it's fine.

[rhutchison]

Should this be here?

[ilanbiala]

@codydaig did you forget to delete lines 7 and 8?

[codydaig]

That is for testing so you can view it on my github pages site.

[lirantal]

what's the issue there? @codydaig

[codydaig]

@lirantal ??

[ilanbiala]

Also, should the _CNAME be changed back to CNAME?

[codydaig]

@ilanbiala - The _CNAME will be changed back before the pull request is ready. That is for testing so you can view it on my github pages site.

[lirantal]

if we fixed the newline stuff and nothing to add then I'm ok with merging.
@codydaig squash commits please when we're done here?

[codydaig]

Newline changes have been made and commits have been squashed.

@ilanbiala I made the new line changes and squashed my commits. Anything else or can this be merged for other people to start contributing?
