Language and i18n

• Updated translations: British English, Chinese (Traditional), Czech, French, Italian, Japanese, Scottish Gaelic, Spanish

Multiplayer server

• Fixed lan_server option not causing the server to exit once vacated, e.g. when using the Host Networked Game option from the Multiplayer menu in the game (issue #3206).

Music and sound effects

• The music now changes immediately when you load a save file (issue #2602).
• Fixed Lua errors when setting a music track that cannot be found when the playlist is already empty, e.g. if there's no music installed for the game (issue #3194).

WML engine

• Removed validation to ensure units cannot have negative hitpoints. We learned that the ability to create such units is documented, and thus disallowing it was an API change. Since API changes aren't allowed in the stable branch, we have reverted it.

Miscellaneous and bug fixes

• Fixed an occasional crash at the loading screen related to multi-thread access of the image cache.
• [kill] animate=yes no longer scrolls to units through fog or shroud, thus matching 1.12's behavior again.
• [message] displays the unit type name when a nameless unit speaks and no custom caption= is specified (issue #3211).
• do_not_list=yes units are no longer excluded from the debug mode-only Create Unit dialog.
• Fixed a rare issue where disabled attacks could cause the wrong attack to be initially selected in the Unit Attack dialog. This bug also had the potential to cause units to the wrong attack when engaging or viewing damage calculations.
• Fixed [scenario] map_file= being unusable in most circumstances.
