Sound is only partially functional, video mode completely nonfunctional, but it makes no sense adjusting them to the current backend code when it's due for replacement.
Reverted this to a sane setting, as it was in the original games and in all other games I have ever seen, i.e. there is a global setting to enable mouse view, and a button to manually trigger it. The toggle can be easily handled by flipping the CVAR directly.
The main problem here was that it triggered a few cases for mouse-less gameplay in the default case with a mouse present, because the mouseaim CVAR was no longer what the game expected.
This misguided change seems to have originated in JFDuke but by now had propagated to all the other games as well, the code was in all 4 frontends.
- hooked up all front ends with a generic message printing function so that common code can access the native message displays. This is needed for consolidation of some input actions which are mostly identical but print messages.
- preparations for a generic message system.
This was consolidated for both EDuke and RedNukem frontends, put into a class with strict access control and the length limit was lifted.
The new class will eventually allow better localization control.
- disabled the mouse movement sensitivity CVARs pending a refactoring of the code to handle them in the input backend instead of the individual input handlers.
Now this was magnitudes easier than the EDuke menu - NBlood's menu is actually clean and usable code but still nothing compared to a unified menu system.
This mainly means being able to use the generic font.
This also adds more generalization to the menu sound handling, plus an option to turn menu sound off. This is motivated by the pig sounds which RR uses in the menu.
* removed some redundant functionality (e.g. Shift-F5 to change - use the console for that!)
* removed a few more leftover parts of the old music system
* savegames should not do more than resuming the music at the point of saving. (DN3D and RR only so far. Blood to be done.)
* handle music enabling/disabling in the backend, which simply knows better what to do. This was only working in the menu, so changing the CVAR had no effect.
* implemented single image screens
* implemented skeleton of the image scroller
* added RR-specific definitions to the menus (need to copy and adjust d_menu.cpp)
* added definitions for credits screens.
