Update documentation to reflect recent changes to architecture and components

[Natkeeran]

As of end of Jan 2017, the CLAW project has undergone significant architecture/components/code organizations changes. READMEs and other documents need to be updated to reflect these changes. Priority could be given to projects that direct users to install and test CLAW.

• https://github.com/Islandora-CLAW/CLAW
  -> Update install link to point to here: https://github.com/Islandora-CLAW/claw_vagrant

• Update CLAW documentation to remove dependencies/components that are no longer required in the core. including Chullo and Crafish

• Update user and developer documentation: "1.x to CLAW" explanatory document #510

@Natkeeran checking in on this and #518; are you working these tickets?

@ruebot I can contribute to Technology Stack documentation about Alpaca and Drupal. Another major area is Fedora and API-X.

http://islandora-claw.github.io/CLAW/user-documentation/intro-to-claw/ does need to be updated. The repo cleanup has helped. This type of work is ongoing, so we can identify some specific tasks and after those are completed, we can close these tickets noting that this work is ongoing.

@Natkeeran great! I've assigned this and #518 to you. Feel free to put in PRs as needed, close existing tickets, and create new ones as needed with defined scope.
