Launcher ignores commands on environment path

[feldrim]

The line below sets the default behavior for process paths as accepting only full paths.

warden/Warden/Core/Launchers/Win32Launcher.cs

Line 16 in ea0f8ed

internal static Regex ProgramPath = new Regex(@"([A-Z]:\\[^/:\*\?<>\|]+\.((exe)))|(\\{2}[^/:\*\?<>\|]+\.((exe)))", RegexOptions.IgnoreCase);

That makes the line below to give exception because "notepad" is called from environment path adn does not include full path.

warden/WardenExample/Program.cs

Line 78 in ea0f8ed

var wardenTest = await WardenProcess.Start("notepad", string.Empty, null);

Until the ProgramPath Regex is modified, the README and WardenExample project can be changed accordingly.
