windows_dpi 0.3.0

Provides an API for marking a process as DPI-aware on windows systems. Works for Windows 7+, using the newer API when available. Also provides a method for getting the DPI appropriate for an HWND. Methods are currently stubs for other platforms, if anybody would like to contribute to support other platforms I'm happy to help!
