When ingame, Shift-Esc would open the menu and another Shift-Esc the
console. Now it immediately opens the console and only Esc without
Shift opens the menu.
When one tries to quit the game (via quit in console) while a timedemo
is running, the game freezes indefinitely while displaying the timedemo
results.
This happens because the MessageBox used for that waits for a an event
normally triggered by a timer - but it seems like that does not happen
anymore during Shutdown()
The fix makes sure that this message box isn't displayed.
Split fs_savepath for config files. This is in preparation for
moving the writable paths on *nix to $XDG_DATA_HOME and
$XDG_CONFIG_HOME.
Affected files: config.spec, *.cfg, doomkey, xpkey.
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.
