Moved Sledgehammer into its own repository, and added a README pointing to it.

While we are at it, move all of Crowbar up a directory, since we no longer
have to seperate it from Sledgehammer like that.
Pre release fixes from Dell Engineering
Add licensing information to files that were missing it.

Also copy curl over very early in the OS install process so that we can
register as installing with the admin node as early as possible.
First pass at making Crowbar not be Ubuntu specific.

Remove the apt repositories and roles from the Crowbar recipie.
We have enough local infrastructure to install packages without them.
More redhat fixups

Run the gem install twice to make sure all deps get nstalled.
Make sure that crowbar recipie does not directly install ipmitool.  It should just ask the ipmi barclamp to do that.

Have the crowbar recipie explicitly create the openstack group and user.
Have the crowbar recipie explicitly include mod_rails
Just include passenger_apache2::mod_rails, it will grab its parent.

Also move the declaration of the openstach user up a bit.
Do not enable auth if we did not set an authentication realm
Do not set a realm if we don't have any users or we do not want security.
Update template to have a null realm by default.
Extra fixups around the null realm checking.
Oops, actually update bc-template-crowbar.schema.
Change capitalize to camelize for proper barclamp name lookup

Add an error helper in the barclamp create proposal path.
Disable Nagios and Ganglia for now.  Porting their recipies will be non-trivial.
Merge in the Ubuntu provisioner changes from Andi.
Merge branch 'master' into redhat-build

Fix up a few merge conflicts on the way to make sure the redhat-build branch
does not load the ubuntu installer stuff or the Ganglia stuff.

Added in Andi's redhat install barclamp and associated changes.
Lie and say that the local system is rubygems.org to enable a slightly more elegant method of installing gems.
Add config.ru to crowbar cookbook
Add a rainbows configuration template
