XML2 Fix v1.7.1

XML2 Fix 1.7.1

The engine half of Legends Classic 0.2.5: bedroom item pictures sit in the first
game's picture window, and heroes are re-stunned by every stun hit.

• Bedroom item pictures: [Game] PersonalItemPicture=window draws a
  personal item's picture as a 256x128 window over the menu's panels, as the
  first game does, instead of stretching it over the whole screen. Absent or
  stock keeps the fullscreen picture.
• Stun per hit: [Game] StunRule=xml1 (gameplay rule 18, now revision 3)
  requests the stun reaction for every stun hit on a party hero, as the first
  game does. Before, a hit during a stun, or just after getting up, was ignored.

Updating Legends Classic: in Ultimate Legends, Rebuild, then Play.
Both PCs need builder 0.2.5 and XML2 Fix 1.7.1; a peer with rule 18
revision 2 (XML2 Fix 1.7.0) is refused by name. The builder enables both
settings. Launcher 0.3.2 already supports this pair; no launcher release is needed.
The save format is unchanged.
