So stuff doesn't look so distorted in widescreen resolutions.
Implies that there are black bars on the left/right then..
Can be disabled with "r_scaleMenusTo43 0"
Does *not* affect the HUD (incl. crosshair) - scaling it automagically
would be very hard (or impossible), because it doesn't only render
the crosshair, healthpoints etc, but also fullscreen effects like the
screen turning red when the player is hit - and fullscreen effects
would look very shitty if they didn't cover the whole screen but had
"empty" bars on left/right.
(Mostly) fixes#188 and #189
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.
