Refactored project file structure for #34

[alvyn279]

Moved settings, wsgi and url admin configs up into main qa_web app, to avoid an abstract inner SA3 folder.

I've tested the functionality of the website and all seems fine, but please take the time to test it out yourselves before reviewing! The components that were touched in the commit are extremely sensitive and critical for our app.

Is the addition of the __init__.py into the base directory really necessary? After all the SA3 directory is not a module, only SA3/qa_web is a module. Feel free to correct me on this

[Lercerss]

After further investigation, the inclusion of SA3/__init__.py is not necessary for the project to function. If there are no other reasons to keep it then I believe we should remove it.
