Hobo edge installation

[Domizio Demichelis]

Instead of waiting for the new gem pushed to rubygems, if you want to use the latest from the repo, you have a better option. I improved the rake :gems task, (now included in the available pre25), so it will be very easy to install hobo-edge for everyone.

[Note for Owen: Adding a paragraph in the book about that could pobably be a good idea.]

This is what you need:

If you need to clone the repo:
$ git clone git://github.com/tablatom/hobo.git [--branch=<branch-name>] [1]

If you have already a cloned repo, just ensure you have the latest:
$ git checkout <branch-name>
$ git pull

Then install the gem locally with:
$ [sudo] rake gems[install]

Please, read the notice at the end of the installation output.

[1] Now <branch-name> is rails3, but it will be master in the near future, so no need to use the --branch option
