I feel that Get-VagrantEnvironment should actually return the environment from the local path rather than the global environment. It just feel more PowerShelly and it's actually what I thought the function would do until I ran it.

Obviously this is a breaking change but as we are at a 0.1.9 build then I feel that change could be made.

To get a global environment I would propose we use a -Global or a -All switch or a Get-VagrantGlobalEnvironment function. My preference is -All.
