Update games/wesnoth to 1.12.5.

Changes:
Version 1.12.5:
 * Campaigns:
   * Eastern Invasion:
     * Fixed scenario events not working right on easy difficulty in 'Captured'.
   * Legend of Wesmere
     * Fixed carryover bugs in scenarios 5-12.
       (units missing from carryover, units appearing twice on map...)
 * Editor:
   * Add Recent Files menu with a list of recently saved or loaded maps or
     scenarios, up to a custom limit (by default 10) that can be set in
     Advanced Preferences.
   * Fixed Player Start labels not being updated with repeat map generations
     (bug #20036)
 * Language and i18n:
   * Updated translations: British English, French, Hungarian, Japanese,
     Latvian, Polish, Portuguese, Scottish Gaelic, Spanish
   * Fixed crashes during start-up on Windows resulting from add-ons containing
     erroneous textdomain declarations (bug #23839).
 * Multiplayer:
   * Era names no longer support formatting markup in the game setup screen.
   * Made MP lobby filter option filter on eras and mods too (bug #22987).
   * Fix scenario ending to early for players that are defeated if there are
     still players fighting and victory_when_enemies_defeated=no.
   * Fix 'enemies defeated' event causing OOS error in mp scenarios.
 * Terrains:
   * Removed unit elevation from N-S hanging bridges
   * Added unit elevation to NW-SE and SW-NE stone chasm bridges

   * Hanging, stone chasm, and plank bridges are now displayed in-game simply
     as "Bridge", retaining their descriptive names in the editor as per
     convention.

messages caused
     by terrains without a minimap image (symbol_image) such as those from the
     Special category in the editor (Impassable Overlay, etc.).
 * User interface:
   * Force uniform font rendering settings across X11 and Apple OS X, avoiding
     color glitches resulting from incorrect applications of subpixel hinting
     (bug #20337).
 * WML engine:
   * Added WML menu item and event handler views to the Gamestate Inspector
     dialog.
   * Removed y offset by -1 from [message]'s scroll-to-unit logic.

   * Fixed strict compilation with clang 3.5 and 3.6.

   * Fixed unbound memory read in internal time formatting code with
     specially-crafted input.
   * Fixed RECRUIT_UNIT_VARIATIONS core WML macro leaking an internal temporary
     variable ($recruited_unit_random_variation).
   * Fixed unit [resistance] and [jamming_costs] not being considered for sync
     check.
   * Fixed OOS on random maps, where clients placed sides in different castles.
   * Several fixes to the handling of key combinations including
     non-alphanumeric keys (Enter, Tab, F1-F12, etc.), especially relevant for
     assigning custom hotkeys to actions in Preferences.

     command-line (bug #20900)
