Docker-Machine installation on Windows can't be found

[MaXal]

Due to the following check in DockerMachineClient:

public boolean isInstalled() {
        return executableExists("docker-machine");
}

docker installation on Windows can't be found. On Windows it's necessary to use "docker-machine.exe" instead of just "docker-machine".

For example, the following code:
Files.isExecutable(FileSystems.getDefault().getPath("C:\\Program Files\\Docker Toolbox\\docker-machine.exe"))
works but
Files.isExecutable(FileSystems.getDefault().getPath("C:\\Program Files\\Docker Toolbox\\docker-machine"))
doesn't.

Hi,
Sorry but I've not worked on Windows support yet - this ought to be noted in the docs, and sorry that you've found out the hard way.

Docker-Machine detection will be one issue; there may potentially be other minor ones too (the volume-based screen recording feature for the selenium module is one thing that springs to mind)

I'd be happy to integrate the changes necessary to make it work, though, but it may take some time for me to do this myself. I'll have a think about this...

Implementation of this needs to take #63 into account as well - there's some simplification possible.

Raised #85 to track Windows support.

@MaXal just to let you know, we have Windows support as an alpha release now - please see docs here if you're interested: http://testcontainers.viewdocs.io/testcontainers-java/usage/windows_support/

@rnorth Thank you! I will definitely check it out.
