Improve installation instructions and automated installation with Fabric #50
Description
A new user should be able to easily install and deploy the FishPi system on a development machine and from there remotely on a RaspberryPi or BeagleBone.
This includes the installation of software that is needed for the installation (Python 2.7, pip, Fabric), as well as Python libraries FishPi depends on while running.
Installation instructions should be provided for multiple operating systems on the development machine (Linux, OSX, Windows?). Fabric and pip simplify the installation process, once they are installed.
