Support for Vagrant 1.0.x Versions

[tknerr]

I have tried to use the Cuken Vagrant steps with Vagrant = 1.0.3, but Cuken implements these steps against the ~> 0.8.7 version.

The Vagrant API changed a bit since then and the steps are no longer compatible, i.e. I get lots of ArgumentErrors and NoMethodErrors when using them with Vagrant 1.0.3:

D:\my-cookbooks\foo>gem list cuken

*** LOCAL GEMS ***

cuken (0.1.22)

D:\my-cookbooks\foo>vagrant -v
Vagrant version 1.0.3

D:\my-cookbooks\foo>cucumber -b
