Support for Windows

[Steven Olsen]

Nice project! Reminds me of https://github.com/princejwesley/Mancy

A Windows installation file would be swell, donchathink? :)

Implementation note. A requirement for this is switching to the expected "close window" behavior. Windows apps are expected to close completely when the main window is closed (as noticed in #15)

#15 is addressed in 516f639, but before I close this I'll run it on a windows machine. After that I'll create a new build.
