Lets also declare the app not to support retina globally (so that framebuffers dimensions are not 2x larger than requested). Note: the window title bar will be blurry, but it’s better than obtaining unreasonably large framebuffer.

Also remove retina option. It makes no sense since it messes all the scintilla mouse selection and doesnt mirror the resolution selection (by nature).

Fake supporting HiDpi for a better window UI appearance in windowed mode.

- Change file structure to separate code from data and 3rdparty binaries.
- Move from make and VS solutions to cmake build system.
