Release 0.3.0
Integration tests now only know about vCloud Core

Not about fog.

Also updates to depend on relevant version of vCloud Core.
Update gitignore to remove dev env specific stuff
Change references to `fog_vms`

This is now called `vms`.
Rename `fog_vm` variables to `vcloud_vm`

For consistency. The important point here is to distinguish the vm that you have retrieved, or retrieved a reference to, via the vCloud API, and the one you are creating. It is not important that fog is used for that.
Update to version of vCloud Core that has change

Release 0.3.0
Bump dependency on vCloud Core version without fog

I did this to avoid later trouble that might be caused by updating vCloud Core to >= 0.10.0 without updating vCloud Tools Tester to >= 0.2.0, as there is a circular dependency. SO I thought I was doing a favour to later developers. However, it turns out that there was a stray inclusion of `vcloud/fog` here, so it's a good job I did this, and actually I'm just finishing the job I started :)

Release version 0.3.1
Refactor Launch to validate in .new, not .run.

Better to do set up and validation when the class is loaded, rather than defer it to when we want to get work done.
