DGEN v1.31 <- v1.30

• Joystick axes can now be configured for controllers with more than two. They can also be reversed.
• Implemented command "calibrate_js" to configure joystick buttons interactively.
• Fixed a bug in the debugger prompt handler.
• Implemented FM2612 debugging support.
• Refactored SDL keyboard handling.
• Removed Linux-specific joystick code which no one uses (not even inLinux, where the SDL version has always been preferred).
• Implemented the ability to bind arbitrary commands to joystick buttons. This makes DGen fully controllable from a joystick/joypad.
• Implemented proper sprite masking. This fixes annoying priority glitches in a number of games.
• Fixed half-submitted commands support in the VDP. This finally fixes the mangled EA logo.
• Some code refactoring and documentation.
• Improved region settings. The single "region" variable can be used to switch interactively from one region settings to another (identifier, resolution, PAL/NTSC mode and frame rate).
• Improved region auto detection with the ability to specify a preference order ("str_region_order" variable).
• Fixed other miscellaneous bugs (NASM on non-x86 targets, uninitialized variables, other warnings and errors).
