AGS: Maniac Mansion Mania (MMM) series keyboard shortcuts issues

[scureuil]

Most "Maniac Mansion Mania" games are written in German/Deutsch at first,
and have shortcut issues with both original Windows AGS engine and ScummVM/AGS-engine.

• For the German language version, the AGS action menu is:

Schau Benutze   Nimm
Öffne Schliesse Gib
Ziehe Drücke    Rede

The game expects this german keyboard layout,
and maps actions position-wise :

[Q] [W] [E] R T Z
[A] [S] [D] E F G
[Y] [X] [C] V B N

(so [E] is a shortcut for "Nimm", and [A] for "Öffne")

But on US keyboards (QWERTY), bottom-leftmost key is Z, not Y,
so the shortcut for "Ziehe" is misplaced.

Worst, French keyboard are like that:

[A]  Z  [E]  R  T [Y]
[Q] [S] [D]  F  G  H
[W] [X] [C]  V  B  N

which gives:

Öffne   *        Nimm * * Ziehe
Shau    Shliesse Gib  * * *
Benutze Drücke   Rede * * *

• The English/Italian/Russian language version uses the US/IT/RU keyboard layout :

[Q] [W] [E] R T Y
[A] [S] [D] E F G
[Z] [X] [C] V B N

which gives the same issue when the user uses a different keyboard layout, both with ScummVM AGS-engine and the original Windows AGS executable.

• For shortcuts to work as expected, raw keycodes should be used instead of keymap-translated keys, and keyboard shortcuts for the action menu should be patched accordingly.

• Affected games:

At least Maniac Mansion Mania 1, 3 to 8 (Maniac Mansion Mania 8 doesn't adapt shortcuts to other languages at all).

Maniac Mansion Mania 2 and 9 use first letter based shortcuts for English language.
