If in_ignoreConsoleKey is set, the console can only be opened with
Shift+Esc, not `/^/whatever, so you can easily type whatever character
is on your "console key" into the game, or even bind that key.
Otherwise, with SDL2, that key (KEY_SCANCODE_GRAVE) always generates the
newly added K_CONSOLE.
in_kbd has a new (SDL2-only) "auto" mode which tries to detect the
keyboard layout based on SDL_GetKeyFromScancode( SDL_SCANCODE_GRAVE ).
Wherever Sys_GetConsoleKey() is called, I now take the current state of
Shift into account, so we don't discard more chars than necessary, esp.
when they keyboard-layout (in_kbd) is *not* correctly set.
(TBH the only reason besides SDL1.2 to keep in_kbd around is to ignore
the char generated by the "console key" in the console..)
Editor also seems to start, didn't test much further.
Only tested 32bit Windows, I fear the editor code isn't 64bit clean..
I hope I haven't broken anything elsewhere..
The console history is saved to a file on quit and restored after
starting the game.
So the commands entered in the console the last times the game was run
are still available in the console-history, just like commands that
were just entered.
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.
