This was done so pm_thirdperson wil always reset to 1 when starting the game. If the game crashes or quits while in first person it was starting back up in it before.
This should fix hdr always resetting every time the game is restarted, thirdperson view sometimes not enabled by default, and the need for pm_modelview to be turned on for cross hair trace line origin fix.
Also cleaned up formatting around hdr cvars, and third person camera cvars.
Enabling the pm_modelview and setting the correct joint in the player.cpp file corrects issues with the trace line used for creating thirdperson crosshair getting cut off early due to objects being to close. Most mostly noticeable shooting around corners.
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.
