If REPRODUCIBLE_BUILD is enabled in CMake, the code will not use
__DATE__ or __TIME__ macros, but instead hardcoded values.
Wherever __DATE__ or __TIME__ were previously used, we now use
ID__DATE__ and ID__TIME__, which are either set to hardcoded values or
to __DATE__ and __TIME__ in neo/framework/Licensee.h.
Added r_aspectratio -1 which means "auto" (as new default).
This mode sets fov_x and fov_y according to screen-width/height.
=> No need to set r_aspectratio manually anymore (assuming your display's
pixels are about square).
The standard aspect ratios can still be enforced as before, though.
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.
