Added opt-in support for high-dpi mode in OS X when on a retina display (resolves issue #761).

Browse Source 
Added a ‘highdpi’ boolean flag to t.window/love.window.setMode (defaults to false.)
When the window is actually in high-dpi mode on a supported display, the graphics width and height and the mouse position are in pixels, rather than ‘window coordinates’.

Added love.window.getPixelScale. Returns the scale factor of the window from user-space points to pixels (e.g. it will be 1 normally, and 2 on a retina display in OS X with high-dpi mode enabled.)
