(GH-30) Allow :node meta-parameter to accept a string

For convenience, the :node meta-parameter now accepts the string of the node
name (from .nodeset.yml) instead of just an RSpecSystem::Node object.

This is more to improve the multi-node usability.

Upgrade to Vagrantfile v2

Updates vagrantfile generation to use the version 2 spec.
Some features in v1 are deprecated in the newer versions
of Vagrant. These Deprecation warnings affect the output of
ssh_config causing rspec-system to fail to configure the VM.

Rework the look and feel to make it pretty and add color

This patch is primarily a look and feel update that improves the visual look of
how tests run. It changes the way `shell` and `rcp` output looks and includes
more color where applicable.

The output now uses the formatters output methods, in a mildly hackish way so
that colors can be disabled centrally and also so if users switch to a different
format the output is silenced. This is useful for cases where you want to run
the progress formatter without all the extra noise for example.

The dividers are now a little better, showing you the begin and end of blocks
in a better way now, so you it is slightly easier to see before/after runs
without them bleeding into the test parts.

As an aside I've also migrated the scp methodology from vsphere to vagrant so
we are using the same channel to transfer files as well as for sending commands
which should in theory be a perf boost, but as yet I've seen little evidence.
