new releases of my favorites gems.

removed puppet from Gem file requirement

this commit also tries to simplify the way we use bundler, in future commits,
we should add more logic of which gems to load based on configration file.

fixes #1574 - ovirt - add remove and show volumes

• volume and interface ordering is now working
• removed include blank because it is a duplicate of the Blank ovirt-template.
• bootable is disabled when editing a vm, because currently I don't handle volume updates. just add and remove of a volume....

Added conditional gem dependency declaration for ruby-debug/ruby-debug19

  requires Ruby 1.8.7.
