Added flexibility when creating the command to be run?

[rogerkk]

I've got my dev environment set up using Vagrant, and would love to have the ability to trigger rspec using this package.

I can run a spec from my host machine using something like the following in my terminal:

vagrant ssh -c 'rspec </path/to/spec>'

Unfortunately I'm not able to build this command using the package. I think the problem would be solved if some variable containing the spec path was exposed and could be used in the "Command" setting, in stead of being appended after what's in that setting.
