Introduce K_CONSOLE, generated by the keyboard's "console key"

Browse source 
regardless of keyboard layout, with a special exemption for layouts
where that key generates a quote character (like the Brazilian one)
because you may wanna type a quote into the console.
(It's SDL_SCANCODE_GRAVE, that key between Esc, 1 and Tab)

The old hack of matching for ^, ~ and ` in Char_Event() didn't work very
well for layouts we didn't anticipate, which is especially relevant with
the recent Scancode fallback, which for example allows binding the ^ key
on Belgian keyboards (which is on SDL_SCANCODE_LEFTBRACKET, far away
from the "console key"), but in that case would *also* open the console.

This is mostly straight-forward, except for a small hack to prevent the
key from generating text input (on German layouts you otherwise get
"^" in the console when closing+opening it), which requires the
"console key" to be pressed without any modifiers like Shift or AltGr.
Yes, it's ugly, but it works and all the uglyness is contained in
IN_Update() and on the other hand Char_Event() becomes less ugly :)
