Update c-pod setup recipe

Change the node identifier to :cpod for ease of development
Add chef-solo setup recipe so c-pod can be updated from itself
Upgrade to jquery 2.1.0
Post reboot network access fixups - TEMPORARY
Updated kickstart files

Removed need for SSI globals for nameservers: use netcfg.cgi to query server
Moved C-Pod yum repository configuration into machine build to avoid catch-22 on chef-solo
Removed 'dev' variants, simply use a recipe or yum to install dev tools. This does require
that chef is available in the C-Pod GEM repository in binary form however.
Update README.md
