Woof! 5.0.0

• Support for the "UMAPINFO" lump has been added, compliant to Rev 1.6 of the spec (@rfomin).
• The concept of compatibility levels has been added, currently offering "Vanilla", "Boom" and "MBF" (default). The default compatibility level may be changed through the menu and overridden with the -complevel parameter, allowing for both numeric and named arguments as in PrBoom+ (@rfomin).
• The comp_3keydoor compatibility flag has been removed for better compatibility with PrBoom+. Fixing this bug is now handled through compatibility levels.
• Mouse button bindings for backward motion and turning right/left have been added.
• Support for recording and playing back Vanilla demos without reduced turning resolution has been added through the -longtics parameter (@rfomin).
• Support for "autoload" directories has been added, both for common ("doom-all") and per IWAD files. WAD files in these directories are loaded before those passed to the -file parameter, DEHACKED files in these directories are processed after those passed to the -deh parameter and before those embedded into WAD files.
• The limit for the values set by the mouse sensitivity thermometers in the menu has been removed.
• The instruction message for multiple choice menu items has been fixed (@rfomin).
• Some portability issues caused by different platforms using either / or \ as directory separators have been fixed (@rfomin).
• The order of the demo sequence has been changed to show the CREDIT graphic screen after the first demo and the port's own credit screen after the second.
• The widescreen offset for the color picker cursor in the menu has been fixed (@rfomin).
• Comments and helps strings are now saved in the correct order in the config file (@rfomin).
• Widescreen graphics for Doom 1 endings have been fixed (@rfomin).
• Boom friction is now properly saved in savegames (@rfomin).
