Create documentation and include it in the distributed installation

[benjaoming]

We should have sphinx and create a static HTML documentation that's bundled and has a desktop shortcut on all user's desktops.

Documentation chapters:

• [x] Introduction
• [ ] ICT centre customization: Local configurations
• [ ] How to:
  • [ ] Create new users
  • [ ] Change passwords
  • [ ] Install printers
  • [ ] Share an internet connection
  • [ ] Add content to the Intranet
  • [ ] Update the server
  • [ ] Change the content hard drive
• [ ] Online community (github etc)

@pdouglass made this initial structure for writing Sphinx documentation in reStructuredText... could you have a look? :)

It will automatically build when we push changes to github and it can be viewed online here:
