WinFellow - Amiga Emulator for Windows Subversion (Archive)

Removed old dx sdk from property sheets because ddraw.lib is included in the windows kits.
And fixed a small sprintf error.

since stat() bug persists in Visual Studio 2015 Update 1, configure project for VS2013
updated release build profile with latest changes to include and linker definition

minor change to fix crash when executed from Amiga Forever in DX11 graphics mode; modes are not being registered properly yet
revert project to Visual Studio 2013

developer documentation updated

Added missing file and allow fallback to feature levels less than DX 11.0, down to 9.1. Still requires DX 11 to be installed. Will allow older cards that don't support DX 11 features to work using the DX 11 API.

Removed some conditional defines that were either obsolete or had no active references in the code.

Reorganised gfxdrv.c to support alternatives to directdraw. Now there is a routing layer (gfxdrv), common functionality (GfxDrvCommon) and directdraw (gfxdrv_directdraw).
Initial DirectX 11 support. Only window by now. Added ui-option and cfg file entry.

re-enable pre-build steps in release build
