Use fog-brightbox gem

[tokengeek]

This changes the dependencies to rely on the fog-brightbox gem which is a module subset of the full fog gem. This has lighter dependencies and requires less code on starting.

Also replaces the now deprecated HandleBoxUrl action with HandleBox following warnings from vagrant 1.5.

Whitespace is also cleaned up.

There might be an issue related to provisioning with vagrant-v0.15.0.dev or earlier.

If I include a provisioning step, vagrant up bombs out.

There was an error talking to the Brightbox cloud. The error
message is shown below:

wrong number of arguments (1 for 3)

Working past the error handling and https://github.com/NeilW/vagrant-brightbox/blob/master/lib/vagrant-brightbox/action/timed_provision.rb#L9 seems to be getting 1 argument now.

This is actually happening on master when testing this as a gem or bundled.

So if you see this it might be an upstream issue. I've just not tracked it down enough to report.

I believe the issue is upstream - hashicorp/vagrant#3226
