[EMU] WinFellow v0.5.4 build 1034

New features:

- re-designed display settings to make use of modern higher resolution displays more intuitive; instead of configuring a window resolution, scaling and overscan area can be configured automatically to create a window of the optimal size and scaling factor; both can also be configured manually to arrive at frequently window sizes
- support for the Direct3D 11 graphics API; this requires DirectX 11 to be installed

• on Windows Vista, the platform update KB971644 should be installed, as it contains required updates to DirectX
• the graphics card has to provide hardware acceleration for Direct3D

- ability to save screenshots to the pictures folder (hit < Print Screen > to trigger)
- support for automatic, as well as 3x and 4x scaling, which is useful for 4K/high DPI displays; for the best results, try leaving the scaling at automatic
- very basic serial port/UART emulation; nothing can be connected to the serial port; this is mostly used for serial debug logging (which is active only in debug builds of WinFellow), but the port is always being emulated

Bug Fixes:

- improved frame timing to present frames in a more evenly paced manner
- improvements to CIA timer handling
- improvements to CPU instruction timing (TAS and PEA instructions)
- fixed sound volume restoration during reset of Amiga session in Amiga Forever
- improved error handling for DMS floppy image extraction
- fixed minor memory leaks
