Add images

I added image and file uploading to articles so we can post documents or images about our project :]

To test, pull down this branch and run 'npm install' from the website directory. You may also have to cd into the 'packages/contrib/socket' directory and run 'npm install' from there. Test that everything works and that files can be uploaded when posting a new article.

I also changed the formatting of how the articles/titles/authors and such appear, let me know if you like it.

NOTE: Only the first 9 Files changed were actually changed by me. The rest were created when I installed mean-upload. So basically when looking to see what changes I made and how I did it, only look at the first 9 files.
